General description

Elastase, Human Neutrophil, CAS 9004-06-2, is a serine protease that degrades elastin, collagen, and proteoglycans
Native elastase from human neutrophil. A serine protease that degrades elastin, collagen, and proteoglycans. Its overexpression has been implicated in the development of pulmonary emphysema, rheumatoid arthritis, and cystic fibrosis.

Warning

Toxicity: Standard Handling (A)

Unit Definition

One unit is defined as the amount of enzyme that will hydrolyze 1.0 µmol of MeO-Suc-Ala-Ala-Pro-Val-pNA (Cat. No. 454454) per min at 25°C, pH 8.0.

Physical form

Salt-free.

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 (-20°C) for long term storage or refrigerate (4°C) for short-term storage. Acidic stock solutions are stable for up to 1 month at 4°C or for up to 1 year at -20°C.
Reconstitute in 50 mM sodium acetate, pH 5.5, with 200 mM NaCl or in other aqueous buffers. Material is most active near a neutral pH, but to maintain stability upon reconstitution, use in a slightly acidic buffer (pH 5.5) to avoid autolysis.

Analysis Note

Major band by SDS-PAGE
