Single B-cell derived. Recombinantly produced.

Recombinant Rabbit Monoclonal Antibodies

Single B-cell discovery captures antibody genes directly from individual antigen-specific rabbit B cells, preserving natural heavy- and light-chain pairing before the selected sequence is locked into recombinant production.

Single B-cell isolation and sequence-defined recombinant rabbit monoclonal antibody production workflow

Turn a stronger discovery process into clearer experimental data

Single B-cell discovery better preserves natural antibody pairing and expands the candidate pool for screening by affinity, specificity, background, and usable signal. Selected clones then move into sequence-defined recombinant production for supported applications including Western blot, immunofluorescence, immunohistochemistry, flow cytometry, immunoprecipitation, and ChIP.

Faithful clone capture

Recover naturally paired antibody genes directly from individual antigen-specific B cells, preserving more of the immune response for screening.

Selection built around assay performance

Evaluate affinity, specificity, background, and usable signal before selecting a clone for supported research applications.

Clone capture

Single B-cell isolation Natural heavy- and light-chain pairingAntibody genes are recovered from the same individual B cell, preserving the pairing selected in vivo.

Traditional hybridoma fusion Fusion creates a selection bottleneckPotentially valuable B cells can be lost when they do not fuse, survive, or expand efficiently.

Clone diversity

Single B-cell isolation Broader access to useful clonesDirect screening is not limited to cells that successfully fuse, survive, and grow as hybridomas.

Traditional hybridoma fusion Available diversity may be narrowerThe final pool is biased toward clones compatible with the fusion and cell-culture process.

Clone continuity

Single B-cell isolation Sequence-defined from the beginningThe selected clone can move directly into recombinant expression for durable identity and future continuity.

Traditional hybridoma fusion Cell-line maintenance adds riskLong-term dependence on a living hybridoma can introduce drift, mutation, or loss of productivity.

Assay flexibility

Single B-cell isolation More flexibility for demanding assaysGreater candidate diversity can improve the chance of finding high-affinity, low-background clones and complementary antibody pairs.

Traditional hybridoma fusion Additional work may be neededSequence recovery, recombinant conversion, and renewed screening can be required to secure long-term reproducibility.

LOD / sensitivity potential

Single B-cell isolation Ultra-highSelects for native, ultra-tight affinity bonds.

Traditional hybridoma fusion VariableUnnatural chain pairing can weaken binding strength.

Sandwich assay pairing

Single B-cell isolation EasyVast clonal diversity provides countless epitope combinations.

Traditional hybridoma fusion DifficultHeavily restricted to common, dominant epitopes.

The recombinant rabbit advantage

Where recombinant mouse can be limiting

Epitope access

The recombinant rabbit advantage Recognize more challenging epitopesRabbit immune diversity can uncover clones against conserved proteins, small antigens, and subtle modifications that may be harder to distinguish in mouse systems.

Where recombinant mouse can be limiting Narrower access to conserved targetsMouse immune tolerance can make some highly conserved mammalian proteins and subtle epitope differences more difficult to target.

Signal potential

The recombinant rabbit advantage Generate stronger, cleaner signalHigh-affinity rabbit clones can improve target detection and support lower working concentrations when matched to the assay.

Where recombinant mouse can be limiting Less headroom for weak-signal assaysWhen affinity or sensitivity is the bottleneck, a rabbit-derived clone may provide a more effective route to a usable signal window.

Clone continuity

The recombinant rabbit advantage Keep the exact clone over timeSequence-defined recombinant production protects clone identity and supports dependable lot-to-lot continuity.

Where recombinant mouse can be limiting Recombinant consistency alone is not enoughA defined sequence preserves the selected clone, but it does not expand the biological diversity of the original mouse immune response.
