MMP-19 proteins act as endopeptidases that degrade multiple components of the extracellular matrix, including aggrecan and cartilage oligomeric matrix protein (comp), during critical developmental processes, hemostasis, and pathological conditions such as arthritis.) plays a key role. In addition to participating in matrix remodeling, MMP-19 may also contribute to neovascularization, or angiogenesis. MMP-19 Protein, Human (solution) is the recombinant human-derived MMP-19 protein, expressed by E. coli , with tag free.
