Technical Data
Matrix Metalloproteinase 9 (MMP-9, Collagenase 4, Gelatinase B)
All cells within tissues are surrounded by an extracellular matrix (ECM) giving the tissues shape and structure. The ECM is constantly being remodeled and constant communication is maintained between cells through this matrix. Secreted proteins, termed matrix metalloproteinases (MMPs), are involved in the modulation of cell matrix interactions. MMPs are Zn(2+) binding endopeptidases that degrade various components of the ECM.
MMPs are enzymes implicated in normal and pathologic tissue remodeling processes, wound healing, angiogenesis, and tumor invasion. MMP9, also known as gelatinase B, is a secreted enzyme which degrades the interstitial collagens, types I, II, and III, and is produced by normal alveolar macrophages and granulocytes. The expression of MMP9 increases in Epstein-Barr virus infected lymphoma derived cell lines and may be of significance in typically invasive nasopharyngeal carcinomas.

Suitable for use in Western Blot, Immunohistochemistry and Immunoprecipitation. Other applications have not been tested.
