Methyltransferases are key players in epigenetic control of gene expression and have become the targets of intensive public and private drug discovery efforts. To accelerate these efforts, BellBrook developed the Transcreener EPIGEN Methyltransferase Assay, a fluorescent SAH detection assay with the sensitivity needed to detect any methyltransferase at physiological SAM concentrations, and the robustness required for industrial HTS. Since its introduction in 2011, the EPIGEN assay has been validated on all of the major instrument platforms and adopted by industrial and academic laboratories worldwide. Now, in response to customer feedback, we have reduced the number of components and simplified the protocol. The performance and response of the simplified assay is identical to the original kit; it contains pre-mixed detection components, so assay set-up is simpler and results are more reproducible.
By utilizing its expertise in HTS assay development, the BellBrook team is able to offer universal, fluorescence based detection of any methyltransferase enzyme that uses SAM as a methyl donor. This approach avoids the complexities and difficulties of detecting specific methylated products. The EPIGEN assay relies on enzymatic conversion of SAH to AMP, which is then detected using the Transcreener® AMP/GMP Assay. It provides robust activity measurements even with very low levels of SAM, while still offering the outstanding deck and signal stability of BellBrook’s Transcreener® Assays. Similar EPIGEN assays are being developed to screen additional epigenetic enzymes, including Histone Acetyltransferases (HATs).
