HDAC class 2a Fluorogenic Assay Kit

Catalog #: 50041
Size: 96 reactions
HDACs regulate cellular processes by catalyzing the hydrolysis of an acetyl group from acetyllysines in modified proteins. In the HDAC assay, fluorescent-dye molecules are attached to a peptide containing acetyllysine. Attachment to the peptide quenches the fluorescence of the dye. After treatment of the peptide with an HDAC, the reaction is mixed with a development solution that is specific for nonacetylated lysines. If the acetyl group has been removed from the lysine by the HDAC, this solution will release the dye allowing for fluorescence. Fluorescence is therefore directly related to HDAC activity.
The Fluorogenic HDAC Class2a Assay Kit is a complete assay system designed to measure histone deacetylase (HDAC) class2a activity for screening and profiling applications. It comes in a convenient 96-well format, with all the reagents necessary for 100 fluorescent HDAC activity measurements. In addition, the kit includes purified HDAC4 and a potent HDAC inhibitor, Trichostatin A, for use as a positive and negative control. The Fluorogenic HDAC Class 2a 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 class2a activity level. First, the HDAC fluorometric substrate is incubated with purified HDAC4 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.

Storage / Stability:

12 months from date of receipt, when stored as directed. Kit components require different storage conditions. Be sure to store each component at the proper temperature upon arrival.

Great for studying enzyme kinetics and screening small molecular inhibitors of HDAC class 2a for drug discovery and HTS applications. This kit is suitable for Class 2a and class 4 HDACs (HDACs 4, 5, 7, 9, 11).
For class 1 and class 2b HDACs ( HDACs 1, 2, 3, 6, 8, 10), we recommend the individual HDAC assay kits or the Fluorogenic HDAC Assay Kits, Cat. #50033 or #50034.
Avoid freeze/thaw cycles.
