Abcam's MMP3 Inhibitor Screening Assay Kit (Colorimetric) (ab139439) is a complete assay system designed to screen MMP3 inhibitors using a thiopeptide as a chromogenic substrate (Ac-PLG-[2-mercapto-4-methyl-pentanoyl]-LG-OC2H5). The MMP cleavage site peptide bond is replaced by a thioester bond in the thiopeptide. Hydrolysis of this bond by an MMP produces a sulfhydryl group, which reacts with DTNB [5,5’-dithiobis(2-nitrobenzoic acid), Ellman’s reagent] to form 2-nitro-5-thiobenzoic acid, which can be detected by its absorbance at 412 nm (ε=13,600 M-1cm-1 at pH 6.0 and above). The assays are performed in a convenient 96-well microplate format
This kit is useful to screen inhibitors of MMP3, a potential therapeutic target. The MMP inhibitor NNGH is also included as a prototypic control inhibitor.
Thiol inhibitors should not be used with this kit, as they may interfere with the colorimetric assay.
