WebbTime course of activation of MMP-9. The MMP-9 proenzyme was incubated with trypsin for various times and the products subjected to SDS/PAGE and electrophoretically … WebbActivation can be obtained in vitro by several agents, such as proteases (trypsin), detergents (SDS), APMA (para -aminophenylmercuric acetate), HgCl 2. Low pH and heat exposure can also lead to activation. One relevant pathway leading to pro-MMP activation in vivo is mediated by plasmin.
