Sirt5 Assay Kit

The Fluorogenic SIRT5 Assay Kit is a complete assay system designed to measure SIRT5 activity for screening and profiling applications. It comes in a convenient 96-well format, with all the reagents necessary for 100 fluorescent SIRT5 activity measurements. In addition, the kit includes purified SIRT5 enzyme and a SIRT inhibitor, Nicotinamide, for use as a positive and negative control, respectively. The Fluorogenic SIRT5 Assay Kit is based on a unique fluorogenic substrate and developer combination. This assay method eliminates dealing with the radioactivity, extraction, and chromatography aspects of traditional assays. Using this kit, only three simple steps on a microtiter plate are needed to analyze the SIRT5 activity level. First, the Sirtuin 5 fluorometric substrate (SIRT substrate 5), containing a succinylated lysine side chain, is incubated with purified SIRT5 enzyme. The desuccinylation sensitizes the substrate so subsequent treatment with the Lysine Developer produces a fluorophore that can then be measured using a fluorescence reader.
