Rabbit Anti-Human MMP2 polyclonal antibody for IHC-P. MMPs are proteolytic enzymes capable of degrading connective tissue components. They have a common mode of activation, a conserved amino acid sequence in the putative metal binding-active site region, and are inhibited by specific tissue inhibitors of metalloproteinases (TIMPs) . MMPa and TIMPs play a significant role in regulating angiogenesis. MMP-2 is synthesized as a 631 amino acid proenzyme which is activated by cleavage of the first 80 amino acids. This antibody reacts with both latent and active MMP-2.
