Active Recombinant Human MMP9

• Cat.No.: MMP9-166H
• Product Overview: Active recombinant matrix metalloproteinase-9 (MMP-9, gelatinase B, 92 kDa type IV collagenase) cloned from human cDNA. The enzyme consists of residues Phe107-Pro449 (NM_004994), which comprises the catalytic/fibronectin domain of human MMP-9, with a C-terminal purification tag. This represents a naturally-occurring active form of MMP-9 which lacks the C-terminal hemopexin domain. Activity toward its targets, such as gelatin, casein, or peptide substrates, is unaffected.

Specification

• Species: Human
• Source: E.coli
• Tag: Non
• Protein Length: 107-449 a.a.
• Description: Proteins of the matrix metalloproteinase (MMP) family are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. Most MMP''s are secreted as inactive proproteins which are activated when cleaved by extracellular proteinases. The enzyme encoded by this gene degrades type IV and V collagens. Studies in rhesus monkeys suggest that the enzyme is involved in IL-8-induced mobilization of hematopoietic progenitor cells from bone marrow, and murine studies suggest a role in tumor-associated tissue remodeling.
• Form: Liquid. In 50mM TRIS, pH 7.5, containing 5mM calcium chloride, 300mM sodium chloride, 20µM zinc chloride, 0.5% Brij-35 and 30% glycerol.
• Bio-activity: XX U/µg. One U=100pmol/min at 37°C using the colorimetric thiopeptolide Ac-Pro-Leu-Gly-S-Leu-Leu-Gly-OEt as substrate. Preincubation of MMP-9 catalytic domain at 1.3nM with the broad-spectrum inhibitor GM6001 at 30nM for 1 hour inhibits enzymatic activity by 97%.
• Molecular Mass: 39 kDa
• Purity: ≥95% (SDS-PAGE)
• Applications: Study enzyme kinetics, cleave target substrates, and screen for inhibitors.
• Storage: -80°C
• Concentration: 0.5µg/µl
