MMP/TACE Substrate, FS-6

The widely used MMP substrate FS-1 (Cat. No. 03-32-5032) is modified by an N-terminal lysine elongation to produce a broad-spectrum MMP and TACE substrate that displays improved water solubility and substrate sensitivities. Exhibits 2- to 9-fold higher specificity constant (k_cat/K_m) towards MMP-1, -8, -13, -14 when compared with FS-1 and ~2-fold higher k_cat/K_m towards TACE when compared with TACE Substrate II and III (Cat. Nos. 616402 and 616403, respectively). It has been used successfully in detecting T98G glioma cell surface-associated MMP activity and is shown to be resistant to proteolysis by human leukocyte elastase, trypsin, and ADAM-10.
