| Description: | HDAC1 and 6 reagents: FLAG-tagged HDACs 1 and 6 were prepared in-house by protein expression in HEK293F cells followed by anti-FLAG affinity purification. 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]. In addition to the above buffer ingredients, TCEP [CalBiochem, catalog #580561, 500 mM stock] was added at a final concentration of 0.5 mM to the buffer for the HDAC6 assays. HDAC1, 2, 3, and 6 enzymes were run at the final concentrations of 0.3 nM, 1.5 nM, 0.3 nM, and 1.333 nM, respectively. Fluor-de-Lys substrate [BioMol Research Laboratories, catalog #KI-104], used to evaluate enzyme activity, was added at the final concentrations of 20 uM, 40 uM, 20 uM, and 2.5 uM for HDACs 1, 2, 3, and 6. To enable detection of the signal, Developer [BioMol Research Laboratories, catalog #KI-105] was added at a 1:250 dilution to the stop solution, which also included 10 uM SAHA [Sigma, catalog #SML0061] to ensure complete termination of the reaction. |
