MMP-14, also known as MT- MMP or MT1-MMP, is a membrane type MMP and contains a transmembrane  domain.  MMP-14 has a role in the activation of the proforms of MMP-2 and MMP-13. Furthermore, MMP-14 is able to directly degrade certain matrix proteins such as laminin, fibronectin, vitronectin and interstitial collagens.  Human MMP-14 consists of 562 amino acid residues including a propeptide of 91 residues. and is most likely intracellularly activated by furin-like enzymes and transported to the membrane as an active enzyme. MMP-14 is thought to be released from the cell membrane by proteolytic cleavage.  The QuickZyme human MMP-14 activity assay enables you to specifically measure active human MMP-14. It can be used for the measurement of MMP-14 activity in various biological samples, such as cultured cells and tissue homogenates.

MMP-14 is believed to be involved in bone and tooth development, tumor cell invasion and cell migration and in shedding of a variety of cell surface proteins.  Recent work points to an involvement of MMP-14 in plaque vulnerability.  A variety of studies show MMP-14 as a biomarker for metastasis and fibrosis in the liver.

Assay Principle

Active MMP-14 Measurement of active human MMP-14 Standards, controls and biological samples are pipetted into the pre-coated plate. Human MMP-14 present in the biological sample is captured by the antibody. After washing, the pro-detection enzyme is added. This is activated by the active MMP-14 into an active detection enzyme. The active detection enzyme is able to cleave the chromogenic substrate, resulting in generation of a yellow color that can be measured at 405 nm using an ELISA plate reader.
