A QUANTIZYME Assay System. The MMP-14 Colorimetric Drug Discovery Kit is a complete assay sytem designed to screen for inhibitors of matrix metalloproteinase-14 (MMP-14, membrane-type matrix metalloproteinase 1, MT1-MMP) using a thiopeptide as a chromogenic substrate. The assays are performed in a convenient 96-well plate format. Also included are active enzyme, a prototypic control inhibitor (NNGH), and a detailed instruction booklet. Alternative name: Membrane type matrix metalloproteinase 1, MT-1 MMP. Applications: Colorimetric detection, HTS Activity assay.
