Product Details
| Alternative Name: | Matrix metalloproteinase 8, Neutrophil collagenase, Collagenase-2 |
| |
| MW: | ~85kDa. |
| |
| Source: | Isolated from stimulated human neutrophil granulocytes (buffy coat). Requires activation. |
| |
| EC: | 3.4.24.34 |
| |
| UniProt ID: | P22894 |
| |
| Concentration: | 100µg/ml |
| |
| Formulation: | Liquid. In 50mM TRIS-HCl, pH 7.0, containing 200mM NaCl, 5mM CaCl2, 1µM ZnCl2, 0.05% BRIJ 35, and 0.05% sodium azide. |
| |
| Purity: | ≥90% (SDS-PAGE) |
| |
| Specific Activity: | ≥60mU/mg protein (Y. Masui, et al.; Biochem. Med. 17, 215 (1977)). One unit is defined as the amount of enzyme that hydrolyzes 1µmol 2,4-dinitrophenyl-Pro-Gln-Gly-Ile-Ala-Gly-Gln-D-Arg-OH per min. at 37°C, pH 7.0. |
| |
| Shipping: | Dry Ice |
| |
| Long Term Storage: | -80°C |
| |
| Use/Stability: | Stable for 1 week when stored at +4°C and for serveral weeks when stored at -20°C. |
| |
| Handling: | Avoid freeze/thaw cycles. |
| |
| Scientific Background: | MMP-8 is a glycoprotein containing complex N-linked oligosaccharides. It hydrolyzes type I over type II, and III collagens. Activated MMP-8 is inhibited by TIMP-1 (Prod. No. ALX-200-426). |
| |
| Technical Info/Product Notes: | Precursor enzyme needs activation using 2mM AMPA (aminophenylmercuric acetate) or 1mM mersalylic acid for 60 min. at 37°C. Alternatively use 0.1mM PCMB (p-chloromercuribenzoate) or 10µg/ml trypsin for 20 min. at 25°C; PCMB is substantially more effective. |
| |
| Regulatory Status: | RUO - Research Use Only |
