Product Overview :
Histone H3-K4 Methylation Assay Kit is use for measuring methylation of histone H3-K4.
Description :
Epigenetic activation or inactivation of genes plays a critical role in many important human diseases, especially in cancer. A major mechanism for epigenetic inactivation of the genes is methylation of CpG islands in genome DNA caused by DNA methyltransferases. Histone methyltransferases (HMTs) control or regulate DNA methylation through chromatin-dependent transcription repression or activation. HMTs transfer 1-3 methyl groups from S-adenosyl-L-methionine to the lysine and arginine residues of histone proteins. SET1, SET7/9, Ash1, ALL-1, MLL, ALR, Trx, and SMYD3 are histone methyltransferases that catalyze Methylation of histone H3 at lysine 4 (H3-K4) in mammalian cells. H3-K4 methylation may serve as a epigenetic mark in euchromatin and mediates activated transcription. Increased H3-K4 methylation is also found to be involved in some pathological processes such as cancer progress. There are only a few methods such as western blot used for measuring histone H3-k4 methylation. The methods available so far are time consuming, labor intensive, or have low throughput. The Histone H3-K4 Methylation Assay Kit addresses these problems by using a unique procedure to measure methylation of histone H3-K4.
Applications :
For specifically measuring histone H3-K4 methylation using a variety of mammalian cells including fresh and frozen tissues, and cultured adherent and suspension cells.
Usage :
For research use only (RUO)
Storage :
Upon receipt: (1) Store GD8 and Methylated H3-K4 Control at –20°C; (2) Store GD3, GD5, GD7, GD9, and 8-Well Assay Strips at 4°C away from light; (3) Store all other components at room temperature. The kit is stable for up to 6 months from the shipment date, when stored properly.Note: Check if wash buffer, GD3, contains salt precipitates before using. If so, warm (at room temperature or 37°C) and shake the buffer until the salts are re-dissolved.
