Deacetylase Inhibitor Cocktail (100X in 70% DMSO)

Deacetylase Inhibitor Cocktail is a mixture of several chemicals with synergistic functions which is designed to maintain the acetylation state of molecules. Among these targets, dynamic changes of histone acetylation caused by HATs and HDACs are the most often occurring. Lysine acetylation is one of the most important post-translational modification which affects protein transcription, DNA replication and repair, cell cycle, and signal transduction pathways. The balance between acetyltransferases and deacetylases affects chromatin condensation, transcription factor activity and protein aggregation, these modification changes attracts significant interests from researchers. Such, Deacetylation Inhibition Cocktail is a useful tool for assays in these important pathways.

Four components of Deacetylase Inhibitor Cocktail: 40μM Trichostatin A, 1mM EX-527, 400 mM nicotinamide and 200mM sodium butyrate. The compounds are solubilized in 70% DMSO. Each has their own specific capacities. Trichostatin A can inhibit class I/II mammalian HDACs. EX-527 inhibits SIRT1 selectively with less activity on SIRT2 and SIRT3. Nicotinamide could act as an inhibitor of sirtuins (SIRT1-7, Class III HDAC). Sodium Butyrate acts against class I/II HDAC competitively.
