Histone Acetyltransferase (HAT) Activity Assay Kit (Fluorometric, Histone H4) (ab239713) utilizes Acetyl CoA and H4 histone peptide as substrates. In this assay, HAT enzyme catalyzes the transfer of acetyl groups from Acetyl CoA to the histone peptide, thereby generating two products - acetylated peptide and CoA-SH. The CoA-SH reacts with the developer and Probe to generate a product that is detected fluorometrically at Ex/Em = 535/587 nm.
The assay can detect HAT activity equivalent to as low as 1.5 U of p300 in a variety of samples.
Storage instructionsStore at -80°C. Please refer to protocols.

RelevanceHistone acetyltransferases (HAT) are enzymes that acetylate conserved lysine amino acids on histone proteins. They have been implicated to play a crucial role in various cellular functions, such as gene transcription, differentiation, and proliferation.
Cellular localizationCytoplasmic and Nuclear. Note=Nuclear in S-phase cells and cytoplasmic.
