Product Overview

The EpiQuik™ Circulating Trimethyl Histone H3K36 ELISA Kit (Colorimetric) is a convenient package of tools that allows the experimenter to specifically measure circulating trimethyl histone H3K36 (H3K36me3) from biological fluid samples such as plasma and serum from human, mouse or rat. The kit has the following advantages:

  • Quick and efficient procedure, which can be finished within 2.5 hours.
  • High sensitivity and specificity. The detection limit is as low as 0.5 ng/well with dynamic range of 1-20 ng/well within the indicated amount range of the plasma/serum. Only recognizes H3K36me3 with no cross-reactivity with unmodified H3 or other modifications at the same lysine site.
  • The control is conveniently included for the quantification of H3K36me3.
  • Strip microplate format makes the assay flexible: manual or high throughput.
  • Simple, reliable, and consistent assay conditions.

Background Information
Epigenetic activation or inactivation of genes plays a critical role in many important human diseases, especially in cancer. A major mechanism for epigenetic gene inactivation is methylation of CpG islands in genomic DNA caused by DNA methyltransferases. Histone methyltransferases (HMTs) control or regulate DNA methylation through chromatin-dependent transcriptional repression or activation. HMTs transfer 1-3 methyl groups from S-adenosyl-L-methionine to the lysine and arginine residues of histone proteins. SETD2 and NSD2 are the major histone methyltransferase that catalyze trimethylation of histone H3 at lysine 36 (H3K36) in mammalian cells. JHDMs and JMJDs are the major histone demethylases that demethylates H3K36. H3K36me3 has been viewed as a signature mark of transcription repression genes, which is placed exclusively in the 5’- region downstream of the promoter. The H3K36me3 can also be changed by inhibition or activation of HMTs. Circulating histone H3K36me3 in plasma or serum has been observed and demonstrated as the marker for many different diseases or pathological changes such as cancer progression. Therefore, detection of circulating H3K36me3 would provide useful information for a better understanding of epigenetic regulation of gene activation and silencing, histone modification-associated pathological processes, screening of disease-related biomarkers, as well as for developing histone modification-targeted drugs.

Principle & Procedure
This kit is designed for measuring total H3K36me3 in plasma or serum. In an assay with this kit, the Histone H3 proteins trimethylated at K36 in the plasma/serum sample are captured on the strip wells coated with anti-H3K36me3 antibody. The captured H3K36me3 proteins can be then recognized with detection antibody followed by a color development reagent. The ratio of H3K36me3 is proportional to the intensity of absorbance. The absolute amount of H3K36me3 can be quantitated by comparing to the standard control.

Starting Materials
Input materials should be plasma or serum. The amount of plasma or serum for each assay can be 10 to 40 µl with an optimal amount of 30 µl.
