| Description: | HDAC-Glo I/II Assay Kit was purchased from Promega Corporation (Madison, Wis.), including the following components: HDAC-Glo I/II Buffer (25 mM Tris buffer, pH 8.0, supplemented with 137 mM: NaCl, 2.7 mM KCl, 1% v/v Triton X-100 and 1 mM: MgCl2), luminogenic substrates Boc-GAK(Ac)-aminoluciferin (HDAC-Glo I/II substrate), proprietary developer reagent (containing trypsin). Assay:The HDAC8 reaction was performed at room temperature in white 384-well polystyrene, flat-bottom microtiter plate (Greiner Bio-one, Monroe, N.C.) in a final volume of 20 μL. Test compounds were first diluted serially in DMSO and 100 nL were transferred to the plate wells by Echo 550 (Labcyte, Sunnyvale, Calif.) before the addition of other reaction components. The final concentration of DMSO in the assay was 0.5%. The HDAC-Glo I/II assay reagent was prepared by rehydration of lyophilized HDAC-Glo I/II substrate in 10 mL. HDAC-Glo I/II assay buffer followed with the addition of 10 μL of developer reagent. 10 uL of 3 nM HDAC8 in the HDAC-Glo I/II assay buffer were first dispensed into the microliter plate containing the compounds and incubated at room temperature for 30 min. The reactions were initiated with the addition of 10 uL HDAC-Glo I/II assay reagent with Multidrop. |
