Anti-TIMP2, clone SPM356

1 mg/ml in 1X PBS, BSA free, sodium azide free. It recognizes a protein of 21kDa, identified as tissue inhibitor of metalloproteinases 2 (TIMP2). It is closely related to TIMP1 and shows the highest binding affinity to both the latent (pro) and active forms of 72kDa Type IV collagenase (also known as MMP2 or gelatinase A). It also has affinity for the active form of 92kDa Type IV collagenase (also known as MMP9 or gelatinase B). TIMP2 inhibits the proteolytic invasiveness of tumor cells and normal placental trophoblast cells. Protein function: Complexes with metalloproteinases (such as collagenases) and irreversibly inactivates them by binding to their catalytic zinc cofactor. Known to act on MMP-1, MMP-2, MMP-3, MMP-7, MMP-8, MMP-9, MMP-10, MMP-13, MMP-14, MMP-15, MMP-16 and MMP-19. [The UniProt Consortium]
