| | Fluor de Lys Assay |
| Description: | Fluor de Lys is a fluorescence based HDAC activity assay comprising a combination of fluorogenic Histone deAcetylase Lysyl substrate and a developer. The kit is a highly sensitive and convenient alternative to radiolabeled, acetylated histones or peptide/HPLC methods for the assay of histone deacetylases. This assay is based on the ability of HeLa nuclear extract, which is enriched in HDAC activity, to mediate the deacetylation of the acetylated lysine side chain of the Fluor de Lys substrate. The assay procedure requires two steps. First, incubation of the HeLa nuclear extract with the Fluor de Lys substrate results in substrate deacetylation and thus sensitizes it to the second step. In the second step, treatment of the deacetylated substrate with the Fluor de Lys developer produces a fluorophore. The substrate-developer reaction, under normal circumstances goes to completion in less than 1 min at 25 C. |
