HDAC Fluorogenic Assay Kit (Gr

The Fluorogenic HDAC Assay Kit is a complete assay system designed to measure histone deacetylase (HDAC) class 1 activity for screening and profiling applications. The kit comes in a convenient 96-well format, with all the reagents necessary for 100 fluorescent HDAC activity measurements. In addition, the kit includes purified HDAC2 enzyme and a potent HDAC inhibitor, Trichostatin A, for use as a positive and negative control. The Fluorogenic HDAC Assay Kit is based on a unique fluorogenic substrate and developer combination. This assay method eliminates dealing with the radioactivity, extraction, and chromatography aspects of traditional assays. Using this kit, only two simple steps on a microtiter plate are needed to analyze the HDAC activity level. First, the HDAC fluorometric substrate, containing an acetylated lysine side chain, is incubated with purified HDAC enzyme. The deacetylation sensitizes the substrate so subsequent treatment with the Lysine Developer produces a fluorophore that can then be measured using a fluorescence reader at 485 nm (excitation)/528 nm (emission). Our other HDAC kit (#50061) contains a substrate that is excited at wavelengths 350-380 nm and fluoresces at wavelengths 440-460 nm. However, the substrate in this kit fluoresces at longer (green) wavelengths: 485 nm(excitation)/528 nm (emission). It is most useful when the sample or inhibitor fluoresces at wavelengths that overlap those of our other HDAC substrate
