Assay Method Information

Assay Name:  Fluorescent Activity Assay
Description:  In vitro HDAC assays were performed using a HDAC fluorescent activity assay kit (Biomol, UK) according to the manufacturer's instructions. Compounds were reduced prior to analysis; 1 mM compound was reduced with 30 mM DTT in DMSO overnight at room temperature, protected from light. Reactions were then set up in a 96-well plate. For each reaction 10 ul compound (5x required concentration in assay buffer) was mixed with 15 ml diluted HeIa Nuclear Extract (30-fold in assay buffer). Serial dilutions were set up for each compound. Reactions containing HeIa extract only and assay buffer only were also set up. 25 ul diluted Fluor de Lys substrate (100-fold in assay buffer) was added to each reaction, which were then incubated at 37C for 1 hour. The reaction was stopped by addition of 50 ul Fluor de Lys Developer (20-fold dilution in assay buffer, plus TSA diluted 100-fold). The reactions were then incubated at room temperature for 10 minutes before fluorescence was measured.
