Description:HDAC assay buffer is an essential reagent for signal generation in HDAC assays performed with any of BPS Biosciences HDAC fluorimetric substrates or assay kits. An appropriate fluorimetric substrate, comprising an acetylated lysine side chain, is first incubated with a sample containing HDAC activity (nuclear or cellular extract, purified enzyme, bead-bound immunocomplex, etc.) in HDAC assay buffer. Deacetylation of the substrate sensitizes it so that, in a second step, treatment with the HDAC assay developer produces a fluorophore. Trichostatin A is included as an ‘inhibitor stop’ for class I and II HDACs. Supplied As: Tris-buffered solution Format: Aqueous buffer solution Instructions for use: In a 50 µL reaction, assay HDAC activity using HDAC (enzyme, lysate, etc.), substrate, HDAC assay buffer, and test inhibitor. Incubate microtiter plate at 37°C for 30 minutes. Add an equal volume (50 µL) of HDAC Assay Developer to each well. Incubate the plate at room temperature for 15 minutes. Read sample in a microtiter-plate reading fluorimeter capable of excitation at a wavelength in the range of 350-380 nm and detection of emitted light in the range of 440-460 nm. \"Blank” value (no enzyme negative control) is subtracted from all other values.
