The FLUOR DE LYS Green SIRT5 Fluorometric Drug Discovery Kit is a complete assay system designed to measure the lysyl desuccinylase activity of the recombinant human SIRT5 included in the kit. A black 96-well microplate is packaged with the kit, but it should be noted that reagents of the FLUOR DE LYS system have also been successfully employed in other formats. The Green SIRT5 Fluorescent Activity Assay is based on the unique FLUOR DE LYS-Succinyl GreenSubstrate/Developer combination. The FLUOR DE LYS-Succinyl GreenSubstrate, which comprises a lysine residue, Nε-succinylated on its side-chains, is first incubated with human recombinant SIRT5 together with the cosubstrate NAD+. Desuccinylation of FLUOR DE LYS-Succinyl Green sensitizes it so that, in the second step, treatment with the FLUOR DE LYS Developer produces a fluorophore. Alternative name: Green sirtuin 5 fluorescent assay kit. Applications: Fluorescent detection, HTS Cell-based assays, Activity assay.
