Alternative name: Matrix metalloproteinase 8, Neutrophil collagenase, Collagenase 2. Purity: ≥90% (SDS-PAGE). Formulation: Liquid. In 50mM TRIS, 5mM CaCl2, 300mM NaCl, 20µM ZnCl2, 0.5% Brij-35, and 30% glycerol. Source: Produced in E. coli. Active Matrix Metalloproteinase-8 (MMP-8, neutrophil collagenase, collagenase-2) catalytic domain from human cDNA. The enzyme consists of the catalytic domain of human MMP-8 (Phe99-Gln269, NM_002424) with a C-terminal purification tag. This represents a naturally-occurring active form of MMP-8 which lacks the C-terminal hemopexin domain1. MMPs lacking this domain cannot cleave native collagens; however, activity toward other targets such as gelatin, casein, or peptide substrates is unaffected. Long Term Storage: -80°C.
