The removal of the acetyl group by histone deacetylases (HDACs) could result in a more tightly compacted, heterochromatin conformation, thus negatively regulating gene expression. Aberrant HDAC activity often correlates with cancer and neurological disorders, therefore, HDAC is widely accepted as an attractive drug target. HDAC inhibitors are already known potential anticancer agents and several HDAC inhibitors have received FDA approval for the treatment of human diseases. Cell-based detection of the activity and inhibition of HDACs is important for clarifying mechanisms of epigenetic regulation of gene activation and silencing, and also beneficial to cancer diagnostics and therapeutics.

Except for Western blot assay, Creative BioMart also performs HDAC-Glo Class I/II cell based assay to rapidly and sensitively evaluate the potency of HDAC inhibitors and selectively profile HDAC inhibitors. The HDAC-Glo I/II assays are highly sensitive, allowing you to obtain a dynamic range of 10- to 100-fold higher than fluorescence methods. HDACs Class I/II from cells, extracts or purified enzyme sources are available for HDAC assay. A variety of cell lines of interest can also be customized and purchased at Creative BioMart.

Procedure of Histone Deacetylase Assays at Creative BioMart

Cells are primarily seeded into each well of the assay plate and treated with various concentrations of tested compound for hours, followed by the addition of HDAC-Glo Class I/II detection reagent to each well of the plate. Subsequently, luminescence signals are recorded. The IC₅₀ (half maximal inhibitory concentration) curve is plotted based on a sigmoidal dose-response equation and the IC₅₀ value is finally calculated.
