General description

Native cathepsin G from human neutrophil. A serine protease that degrades collagen and proteoglycans. Has been implicated in connective tissue diseases such as emphysema and rheumatoid arthritis. Acts as a potent agonist of human platelet activation leading to their aggregation. Reported to be involved in the activation of pro MMP-2 via mechanism requiring MT1-MMP. Inhibited by chymostatin, DFP, and Z-Phe-CH2Br. Reconstitute in 150 mM NaCl, 50 mM sodium acetate buffer, pH 5.5.

Warning

Toxicity: Standard Handling (A)

Unit Definition

One unit is defined as the amount of enzyme that will hydrolyze 1.0 µmol of Suc-AAPF-pNA per min at 25°C, pH 7.5.

Preparation Note

Prepared from blood that has been shown by certified tests to be negative for HBsAg and for antibodies to HIV and HCV.

Reconstitution

Following reconstitution, aliquot and freeze (-70°C) for long term storage or refrigerate (4°C) for short term storage. Stock solutions are stable for up to 1 week at 4°C or for up to 6 months at -70°C.
Reconstitute in 50 mM NaOAc and 150 mM NaCl, pH 5.5.
