PRMT5 is a histone methyltransferase that exhibits methylation activity toward H4-R3.Intended Use:Suitable for studying enzyme kinetics and HTS applications.Test Principle:The PRMT5 Chemiluminescent BioAssay Kit is designed to measure PRMT5 activity for screening and profiling applications. The PRMT5 Chemiluminescent BioAssay Kit comes in a convenient format,with a 384-well plate precoated with histone H4 peptide substrate,the antibody against methylated arginine3 residue of Histone H4,the secondary HRP-labeled antibody,S-adenosylmethionine,methyltransferase assay buffer,and purified PRMT5 enzyme for 384 enzyme reactions. The key to the PRMT5 Chemiluminescent Assay Kit is a highly specific antibody that recognizes methylated R3 residue of Histone H4. With this kit,only three simple steps on a microtiter plate are required for methyltransferase detection. First,S-adenosylmethionine is incubated with a sample containing assay buffer and methyltransferase enzyme. Next,primary antibody is added. Finally,the plate is treated with an HRP-labeled secondary antibody followed by addition of the HRP substrate to produce chemiluminescence that can then be measured using a chemiluminescence reader.Contraindications: DMSO >1%,strong acids or bases,ionic detergents,high saltKit Components:PRMT5/MEP50 human enzyme,1x40ug100uM S-adenosylmethionine,1x250ulPrimary antibody 4-3,1x100ulSecondary HRP-labeled antibody 2,2x10ul4x PRMT5 assay buffer (add DTT before experiment),2x3mlBlocking buffer,2x50mlHRP chemiluminescent substrate A (transparent bottle),2x6mlHRP chemiluminescent substrate B (brown bottle),2x6ml384-well plate precoated with histone substrate,1x plateStorage and Stability:Store powder at 4°C liquid at -20°C.
