CAS: 39445-21-1, elastase (porcine pancreas), elastase, pancreatin peptidase E, pancreatin peptidase I, elastase, pancreatic elastase, elastase, Elastase English name: Elastase, pancreatic from porcine pancreas; Pancreatopeptidase E; Elastase Other names: elastase; pancreatin E; pancreatin I; elastase; pancreatic elastase; elastase CAS number: 39445-21-1 grade: Highly chromatographically purified activity: ≥ 8units / mg vitality definition: One unit will hydrolyze 1.0 μmole of N-succinyl-L-Ala-Ala-Ala-p-nitroanilide per min, pH 8.0 at 25 ℃ Unstable: <pH3.5 Properties: white needle crystal or micro Yellow lyophilized powder. Molecular weight 25000 (pancreas). Dissolved in water, it is a broad-spectrum proteolytic enzyme characterized by decomposition of insoluble elastin. It can be extracted from animal pancreas or prepared by microbial fermentation. Elastase extracted and purified from animal pancreas is an endopeptidase, containing 240 amino acid residues, isoelectric point PI9.5, optimal pH 8.1 ～ 8.8, at 4 ～ 6 ℃, PH value 5 ～ 10 The enzymatic activity can be maintained for several days. The lyophilized powder can be stored for 6 to 12 months below 5 ° C. It can be inactivated when it encounters strong acids and can catalyze the hydrolysis of other peptide bonds formed by elastin peptidase or neutral amino acids. Uses: biochemical research. Microbial elastase, like pancreatic elastase, has a wide range of hydrolysis properties, not only can degrade elastin, but also can decompose a variety of proteins such as casein, gelatin, fibrin, hemoglobin, albumin, etc. It is a broad spectrum Endopeptidase. This enzyme can increase the activity of lipoproteinase, and has the function of lipoproteinase A, which can prevent the synthesis of cholesterol in the body and promote its conversion to cholic acid. Storage: -20 ℃
