Assay Method Information

Assay Name:  Enzymatic Assay
Description:  HDAC5 reagents: N-terminal GST tagged HDAC5 was purchased from BPS Bioscience [catalog #50045]. Assays were performed with buffer containing 20 mM HEPES, pH 8.0 [Boston BioProducts, catalog #BB-104, 1M stock], 137 mM NaCl [Sigma, catalog #S5150, 5M stock], 2.7 mM KCl [BioChemika, catalog #87526, 4M stock], 1 mM MgCl2 [Fluka, catalog #63020, 1M stock], and 0.05% BSA (Fraction V) [Invitrogen, catalog #15260, 7.5% stock]. The HDAC5 enzyme was run at the final concentration of 0.447 nM. Boc-Lys(TFA)-AMC substrate [Bachem, catalog #1-1985.0050], used to evaluate enzyme activity, was added at the final concentration of 60 uM. To enable detection of the signal, Developer II [BioMol Research Laboratories, catalog #KI-176] was added at a 1:200 dilution to the stop solution, which also included 20 uM trichostatin A (TSA) [Sigma, catalog #T8552] to ensure complete termination of the reaction.
