Product Overview

Background
This gene encodes a member of the dishevelled (dsh) protein family. The vertebrate dsh proteins have approximately 40% amino acid sequence similarity with Drosophila dsh. This gene encodes a 90-kD protein that undergoes posttranslational phosphorylation to form a 95-kD cytoplasmic protein, which may play a role in the signal transduction pathway mediated by multiple Wnt proteins. The mechanisms of dishevelled function in Wnt signaling are likely to be conserved among metazoans.

Applications

Suggested protocols for DVL2 Polyclonal Antibody should be self-optimized according to the user's experiment.

Choose Your IF/ICC Workflow

Use this immunofluorescence (IF) and immunocytochemistry (ICC) protocol guide to run fluorescent antibody staining in cultured cells, tissue sections, multiplex panels, and phospho/PTM target workflows.

Cultured cell IF/ICC protocol

Use this workflow for fluorescent antibody staining of adherent or suspension cells on coverslips, chamber slides, or imaging plates.

  • Use this format when: Detecting protein localization, nuclear markers, cytoplasmic proteins, histone marks, signaling proteins, or cell morphology in cultured cells.
  • Optimize first: Fixation method, permeabilization strength, blocking buffer, primary antibody dilution, and imaging exposure.
1
Plate cells
Seed cells onto sterile coverslips, chamber slides, or imaging plates so they reach 50-80 percent confluence on staining day. For coverslips in a 24-well plate, use enough medium to fully cover the cells.
2
Fix cells
Remove medium and gently rinse once with PBS. Add 4 percent paraformaldehyde in PBS for 10-15 minutes at room temperature. For some cytoskeletal, membrane, or epitope-sensitive targets, compare with cold methanol fixation for 5-10 minutes at -20 degrees C.
3
Wash and permeabilize
Wash 3 times with PBS, 5 minutes each. Permeabilize with 0.1-0.3 percent Triton X-100 in PBS for 5-10 minutes at room temperature. For nuclear histone or chromatin targets, 0.2-0.5 percent Triton X-100 can be tested. For membrane targets, reduce or omit detergent.
4
Block nonspecific binding
Add blocking buffer, such as 1-5 percent BSA or 5 percent normal serum in PBS with 0.05-0.1 percent Tween-20. Incubate 30-60 minutes at room temperature. Use serum from the host species of the secondary antibody when practical.
5
Add primary antibody
Dilute DVL2 Polyclonal Antibody in blocking buffer. Start with the datasheet-recommended IF/ICC dilution or test 1:100, 1:250, and 1:500. Add enough volume to cover the sample, such as 100-200 uL per coverslip or 50-100 uL per chamber well. Incubate 1 hour at room temperature or overnight at 4 degrees C in a humidified chamber.
6
Wash after primary antibody
Wash 3 times with PBS or PBST, 5 minutes each, using gentle rocking. Do not allow cells to dry.
7
Add fluorescent secondary antibody
Dilute fluorophore-conjugated secondary antibody in blocking buffer, commonly 1:500-1:1000. Add enough volume to cover the cells and incubate 45-60 minutes at room temperature protected from light.
8
Counterstain and mount
Wash 3 times. Add DAPI or another nuclear counterstain for 5 minutes if desired, then wash once. Mount coverslips with antifade mounting medium and cure according to the mountant instructions.
9
Image and document settings
Acquire images using the same exposure, laser power, gain, and offset for samples that will be compared. Include no-primary and secondary-only controls to evaluate background.
Fixation choiceParaformaldehyde preserves morphology well. Methanol can improve some cytoskeletal or nuclear epitopes but may disrupt membrane morphology.
AutofluorescenceIf background is high, reduce fixation time, improve washing, test a different blocking buffer, or switch fluorophores.

Tissue immunofluorescence protocol

Use this workflow for fluorescent antibody staining of frozen, fixed frozen, or FFPE tissue sections.

  • Use this format when: Detecting spatial protein expression in tissue sections with fluorescence rather than chromogenic IHC.
  • Optimize first: Section type, antigen retrieval, autofluorescence control, permeabilization, antibody dilution, and mounting medium.
1
Prepare sections
Use 4-8 um tissue sections mounted on charged slides. Air dry frozen sections for 10-20 minutes. For FFPE sections, deparaffinize through xylene and graded ethanol, then rehydrate to water.
2
Fix or retrieve antigen
For frozen sections, fix with cold acetone for 10 minutes or 4 percent paraformaldehyde for 10-15 minutes depending on the target. For FFPE sections, perform heat-induced antigen retrieval in citrate buffer pH 6.0 or Tris-EDTA pH 9.0 for 10-20 minutes, then cool 20 minutes.
3
Reduce autofluorescence if needed
For tissue with high autofluorescence, treat with an autofluorescence quenching reagent or freshly prepared 0.1 percent sodium borohydride for 5-10 minutes, followed by thorough PBS washes. Choose the method compatible with your fluorophores.
4
Permeabilize and block
Permeabilize with 0.1-0.3 percent Triton X-100 in PBS for 5-10 minutes if intracellular or nuclear access is needed. Block 30-60 minutes with 5 percent normal serum or 1-5 percent BSA in PBS.
5
Add primary antibody
Dilute DVL2 Polyclonal Antibody in blocking buffer. Start with the datasheet-recommended tissue IF dilution or test 1:100, 1:250, and 1:500. Apply 100-200 uL per section, cover with parafilm or use a humidified chamber, and incubate 1-2 hours at room temperature or overnight at 4 degrees C.
6
Wash and add secondary antibody
Wash 3 times for 5 minutes each in PBS or PBST. Add fluorophore-conjugated secondary antibody diluted 1:500-1:1000. Incubate 45-60 minutes at room temperature protected from light.
7
Counterstain and mount
Wash 3 times. Add DAPI if desired. Mount with antifade medium and coverslip carefully to avoid bubbles.
8
Image sections
Use identical microscope settings for comparative samples. Include no-primary controls and known positive tissue when available.
Tissue handlingDo not let sections dry after rehydration or blocking begins.
RetrievalSome epitopes require retrieval for FFPE tissue but not frozen tissue. Test pH 6 and pH 9 retrieval when starting a new antibody.

Multiplex IF/ICC protocol

Use this workflow to detect two or more targets in the same cells or tissue section using spectrally distinct antibodies.

  • Use this format when: Comparing colocalization, marker identity, signaling state, or target expression in the same sample.
  • Optimize first: Host species compatibility, fluorophore separation, antibody order, blocking, cross-reactivity controls, and exposure settings.
1
Plan antibody panel
Choose primary antibodies from different host species when possible. Match secondary antibodies to non-overlapping fluorophores. Avoid fluorophores with heavy spectral overlap unless spectral unmixing is available.
2
Fix, permeabilize, and block
Prepare the sample using the IF/ICC or tissue IF fixation and blocking conditions appropriate for the most sensitive target. Use enough blocking buffer to reduce nonspecific secondary antibody binding.
3
Add primary antibody mix
Prepare a master mix containing each primary antibody at its optimized dilution. Include DVL2 Polyclonal Antibody if it is one of the targets in the panel. Start with single-stain optimized dilutions before combining antibodies. Incubate 1 hour at room temperature or overnight at 4 degrees C.
4
Wash thoroughly
Wash 3 times for 5 minutes each with PBS or PBST. Extend washes to 5-10 minutes when background or cross-channel signal is high.
5
Add secondary antibody mix
Add cross-adsorbed secondary antibodies diluted in blocking buffer, commonly 1:500-1:1000. Incubate 45-60 minutes protected from light.
6
Counterstain and mount
Wash 3 times. Add nuclear counterstain if needed, then mount with antifade medium compatible with all fluorophores.
7
Acquire controls
Image single-color controls, no-primary controls, and full-stain samples using consistent settings. Use single-color controls to identify bleed-through or compensation needs.
Same-species primariesIf two primary antibodies share the same host species, use directly conjugated primaries, sequential staining with blocking, Fab fragments, or tyramide signal amplification when appropriate.
ColocalizationDo not call colocalization from overexposed images. Keep all channels below saturation.

Phospho/PTM IF protocol

Use this workflow for phosphorylation, acetylation, methylation, ubiquitination, or other modification-specific antibody staining.

  • Use this format when: Detecting transient signaling or post-translational modifications in cells or tissue.
  • Optimize first: Sample timing, inhibitor use, fixation speed, permeabilization, antibody dilution, and positive or negative treatment controls.
1
Prepare treated and control samples
Plan untreated, stimulated, inhibited, knockdown, or positive control samples before staining. For phospho targets, add phosphatase inhibitors during washes or lysis-related steps where applicable and fix quickly after treatment.
2
Fix rapidly
Remove medium and rinse briefly with warm PBS when needed. Fix with 4 percent paraformaldehyde for 10-15 minutes at room temperature, or use methanol fixation for targets known to work better with alcohol fixation.
3
Permeabilize for nuclear or intracellular access
Wash 3 times. Use 0.1-0.3 percent Triton X-100 for 5-10 minutes. For histone or chromatin PTMs, test 0.2-0.5 percent Triton X-100 and consider a short pre-extraction step only if compatible with morphology and the target.
4
Block
Block 45-60 minutes with 1-5 percent BSA in PBS or TBS. For phospho-specific antibodies, BSA is often preferred over milk because milk can contain phosphoproteins that increase background.
5
Add primary antibody
Dilute DVL2 Polyclonal Antibody in blocking buffer. Start with the datasheet-recommended IF dilution or test 1:100, 1:250, and 1:500. Incubate overnight at 4 degrees C for low-abundance PTMs or weak signals.
6
Wash and detect
Wash 3 times for 5 minutes. Add fluorophore-conjugated secondary antibody at 1:500-1:1000 for 45-60 minutes protected from light. Wash 3 times.
7
Mount and image
Counterstain if needed, mount with antifade medium, and image positive and negative controls with the same settings. For signal quantification, avoid saturated pixels and analyze the same cellular compartment across samples.
PTM specificityUse inhibitor, stimulation, peptide competition, knockdown, or known positive/negative controls when available to support modification-specific interpretation.
Blocking bufferIf background is high, compare BSA, serum, fish gelatin, or commercial antibody diluent.

Choose Your ELISA Format

Use this ELISA protocol guide to choose and run a plate-based immunoassay workflow. Select sandwich, indirect, direct, or competitive ELISA to view detailed benchtop starting conditions, including coating, blocking, washing, antibody incubation, detection, plate reading, controls, and troubleshooting.

Sandwich ELISA protocol

Use this workflow when a target is captured by one antibody and detected by a second antibody that recognizes a different epitope.

  • Use this format when: Quantifying low-abundance soluble antigens in complex biological matrices where a compatible matched antibody pair is available.
  • Optimize first: Capture antibody concentration, detection antibody concentration, sample dilution, blocking buffer, wash stringency, standard curve range, and matrix effects.
Sample types
  • Best sample types: Serum, plasma, saliva, culture supernatants, and tissue homogenates.
  • Best for: Quantifying low-abundance antigens, such as cytokines, hormones, and biomarkers, in complex biological matrices.
  • Accuracy note: Sandwich ELISA is usually not the best choice for very small or single-epitope analytes because two non-overlapping antibody binding sites are needed.
1
Prepare plate map and reagents
Plan standards, blanks, negative controls, positive controls, and samples before starting. Bring coated plate, standards, samples, wash buffer, blocking buffer, detection antibody, enzyme conjugate, substrate, and stop solution to room temperature unless the kit manual says otherwise. For manual coating, use a high-binding 96-well ELISA plate.
2
Coat capture antibody
Dilute capture antibody in carbonate-bicarbonate coating buffer, pH 9.6, or the buffer specified for the antibody pair. Add 100 uL per well. Cover the plate and incubate overnight at 4 degrees C, or 2 hours at room temperature as a faster starting condition. Aspirate the coating solution after incubation.
3
Wash and block
Wash 3 times with 250-300 uL per well 1x PBST or TBST. Add 200 uL per well blocking buffer, such as 1-5 percent BSA, casein, or nonfat dry milk in PBS/TBS. Incubate 1 hour at room temperature. Wash 3 times.
4
Add standards and samples
Prepare standards in duplicate or triplicate using the recommended diluent. Dilute samples so readings fall within the linear range. For cell lysates or tissue homogenates, prepare clarified samples and include fresh protease inhibitor during upstream extraction when compatible with the assay, such as R-1101 Protease Inhibitor Cocktail. Add 100 uL per well and incubate 1-2 hours at room temperature, or overnight at 4 degrees C for low-abundance targets. Wash 4-5 times.
5
Add detection antibody
Dilute detection antibody in assay diluent. If this product is used as the detection antibody, add DVL2 Polyclonal Antibody at the datasheet-recommended dilution or start at 0.25-2 ug/mL for optimization. Add 100 uL per well and incubate 1 hour at room temperature. Wash 4-5 times.
6
Add enzyme conjugate and substrate
Add 100 uL per well HRP-conjugated secondary antibody, or R-1098 Streptavidin: HRP Conjugate when the detection antibody or binding reagent is biotin-labeled. Incubate 30-60 minutes at room temperature protected from light when needed. Wash 5 times, then add 100 uL TMB substrate per well.
7
Stop and read
Develop color for 5-20 minutes until the standard curve is visible but not saturated. Add 50-100 uL stop solution per well and read absorbance at 450 nm, with 570 or 620 nm correction if available. Analyze standards with a 4-parameter logistic curve when appropriate.
ControlsInclude blank wells, zero standard, standard curve, matrix control, no-sample control, and positive sample when available.
Wash consistencyMost high background in sandwich ELISA comes from insufficient washing, over-concentrated detection antibody, or incompatible blocking buffer.

Direct ELISA protocol

Use this workflow when the target is immobilized or captured and detected directly by a labeled antibody, direct detection reagent, or kit-specific detection system.

  • Use this format when: A direct detection kit, directly labeled antibody, purified antigen, semi-purified antigen, or target-specific direct detection reagent is available.
  • Optimize first: Coating or sample input, target purity, detection reagent amount, incubation time, wash stringency, and substrate development time.
Sample types
  • Best sample types: Purified or semi-purified antigens, recombinant proteins, and clarified cell or tissue lysates when target coating and background are acceptable.
  • Best for: Screening antibody specificity or confirming the presence of an antigen in an isolated, high-purity state.
  • Accuracy note: Direct ELISA is simple and fast, but it is less ideal for crude complex matrices because non-target proteins can compete for plate binding and increase background.
1
Prepare plate and samples
Plan standards, blanks, negative controls, positive controls, and sample dilutions. For manual direct ELISA, use purified or semi-purified antigen, recombinant protein, or clarified lysate only when plate coating and background are acceptable. Add 100 uL per well of standards or samples according to the kit format or coating requirement.
2
Immobilize target if required
For coated-plate direct ELISA, incubate antigen or sample in the well overnight at 4 degrees C or 2 hours at room temperature. For direct target-detection kits, follow the kit manual for binding, capture, or sample incubation conditions.
3
Wash and block
Wash 3 times with 250-300 uL per well wash buffer. Add 200 uL per well blocking buffer for 30-60 minutes if the assay format requires blocking. Some direct detection kits include a proprietary blocking or assay buffer that should be used instead.
4
Add direct detection reagent
Add 100 uL per well of the directly labeled antibody, direct detection reagent, or enzyme-conjugated target-specific reagent. If using a directly conjugated antibody, start with the datasheet-recommended dilution or test 0.1-1 ug/mL. Incubate 30-90 minutes at room temperature protected from light when appropriate.
5
Wash and develop
Wash 4-5 times to reduce background. Add 100 uL per well substrate. Develop until standards or positive controls show clear separation without saturation.
6
Stop and read
Add 50-100 uL stop solution when using TMB and read at 450 nm. Use the correction wavelength recommended for the plate reader if available. Compare results to the standard curve or kit-specific calculation method.
Direct detection kitsSome EpigenTek assay kits use direct target-detection formats for small molecules, DNA/RNA damage markers, or epigenetic modifications. In those cases, the kit manual overrides generic antibody-only workflow assumptions.
Background controlInclude blank, no-target, no-detection-reagent, and positive control wells when compatible with the kit or assay design.

Indirect ELISA protocol

Use this workflow to detect antibody binding to an immobilized antigen or target molecule using an unconjugated primary antibody and labeled secondary antibody.

  • Use this format when: Measuring antibody binding, total antibody concentration, titer, or immune response to a coated antigen.
  • Optimize first: Antigen coating concentration, sample or antibody dilution, blocking buffer, secondary antibody dilution, and wash stringency.
Sample types
  • Best sample types: Serum, plasma, saliva, and other body fluids.
  • Best for: Measuring total antibody concentrations, titers, or screening immune responses against specific pathogens or antigens.
  • Accuracy note: Match the secondary antibody to the sample antibody species and isotype, and validate saliva or other non-serum matrices before relying on quantitative comparisons.
1
Coat antigen or target
Dilute purified antigen, peptide, protein, histone, modified target, cell lysate, or other coating material in carbonate-bicarbonate buffer or PBS. Add 100 uL per well. A common starting range is 0.5-5 ug/mL for purified protein or peptide. If the antigen or capture reagent is biotinylated, a streptavidin-coated plate such as R-1102 Streptavidin-Coated Strip Microwell Plate may be used instead of passive coating. Incubate overnight at 4 degrees C or 2 hours at room temperature.
2
Wash and block
Aspirate coating solution and wash 3 times with 250-300 uL per well PBST or TBST. Add 200 uL per well blocking buffer. Incubate 1 hour at room temperature, then wash 3 times.
3
Add primary antibody
Dilute DVL2 Polyclonal Antibody in assay diluent. Start with the datasheet-recommended dilution when available; otherwise test a dilution series such as 1:250, 1:500, 1:1000, and 1:2000. Add 100 uL per well and incubate 1 hour at room temperature or overnight at 4 degrees C for weak targets.
4
Wash after primary antibody
Wash 4-5 times with 250-300 uL per well wash buffer. Tap the inverted plate on clean absorbent material after the final wash to remove residual liquid without drying the wells.
5
Add enzyme-conjugated secondary antibody
Dilute HRP- or AP-conjugated secondary antibody in assay diluent, commonly 1:2000-1:10000 depending on supplier and signal strength. For common mouse or rabbit primary antibodies, host-matched options include A12003 HRP-Goat Anti-Mouse Secondary Antibody or A12004 HRP-Goat Anti-Rabbit Secondary Antibody. Add 100 uL per well and incubate 30-60 minutes at room temperature.
6
Develop signal
Wash 5 times. Add 100 uL substrate per well. For HRP/TMB, develop 5-20 minutes protected from strong light, then stop with 50-100 uL stop solution and read at 450 nm.
7
Interpret results
Subtract blank background and compare signal across antigen-coated, uncoated, no-primary, and no-secondary controls. High signal in no-primary wells suggests secondary antibody or blocking-related background.
Antigen coatingToo much coated antigen can increase background. If the signal is high but nonspecific, reduce coating concentration before changing everything else.
Primary antibody variableThe product page can replace the primary antibody variable in this protocol with the selected antibody name.

Competitive ELISA protocol

Use this workflow when sample target competes with immobilized or labeled target for antibody or binding reagent.

  • Use this format when: The analyte is small, has one dominant epitope, or is measured by competition rather than two-antibody sandwich capture.
  • Optimize first: Sample dilution, competitor concentration, antibody concentration, incubation time, standard curve range, and matrix interference.
Sample types
  • Best sample types: Serum, plasma, saliva, culture supernatants, and crude biological fluids.
  • Best for: Detecting small molecules, hormones, or targets with only a single antigenic epitope.
  • Accuracy note: Competitive ELISA produces an inverse signal, so higher analyte levels usually give lower absorbance or fluorescence.
1
Prepare standards and samples
Prepare a full standard curve using the assay diluent recommended for the target. For serum, plasma, saliva, culture supernatants, or crude biological fluids, dilute samples into the same matrix when possible. Competitive assays often need careful sample dilution because high target concentration produces lower signal.
2
Add standards, samples, and competitor
Add 50-100 uL per well of standards or samples according to the assay design. Add competitor, tracer, or labeled target reagent if the protocol requires a pre-mix. Mix gently without splashing.
3
Add antibody or binding reagent
Add the antibody or target-specific binding reagent at the optimized concentration. When using an antibody-based format, add DVL2 Polyclonal Antibody only if the product is the intended competitive binding antibody and follow the datasheet dilution first.
4
Incubate competition reaction
Incubate 1-2 hours at room temperature, or as specified by the kit manual. Keep incubation times consistent across the plate because competitive assays are especially sensitive to timing differences.
5
Wash thoroughly
Wash 4-5 times with 250-300 uL per well wash buffer. Avoid drying the wells. Inconsistent washing can distort the inverse standard curve.
6
Develop and read
Add 100 uL substrate per well and develop until the low-analyte standards produce strong but unsaturated signal. Stop and read at the appropriate wavelength. Fit the data using the curve model recommended by the kit or assay format.
Signal directionIn competitive ELISA, stronger sample target usually means lower signal. Label graphs and reports clearly to avoid reversed interpretation.
TimingUse a multichannel pipette and consistent timing between rows when possible.
