弹性蛋白酶_人类中性粒细胞来源

MW: 29,500
Extinction Coefficient: 0.985

Salt-free lyophilized solid.

Reconstitution: After centrifugation, we suggest addition of 50 mM Na Acetate, pH 5.5, with 150 mM NaCl to the original volume, followed by gentle mixing to ensure adequate homogenization.

Storage:

This enzyme degrades elastin, collagen, and proteoglycan and has been implicated in the development of pulmonary emphesema and rheumatoid arthritis.

Ref: Baugh, R.J. and Travis, J. 1976. Biochemistry. 15,836; Bode, W. et Al. 1986. EMBO J. 5 (10), 2453

Activity: 20-22 units per mg protein. One unit is defined as the amount of enzyme that hydrolyzes one umole of MeO-Suc-Ala-Ala-Pro-Val-pNA per minute at 25oC, pH 7.5.

Purity: >=95% by SDS-PAGE

Prepared from whole blood shown to be non reactive for HBsAg, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA-required tests.

Lab products are laboratory reagents and are not to be administered to humans or used for any drug purpose. For research use only.
