Protamine sulfate

Other names: Protamine sulfate

CAS No.: 53597-25-4

Molecular weight: ≤ 1000

Grade: br

Protein content: ≥ 98%

Loss on drying: ≤ 8%

Ash content: ≤ 7%

Physicochemical properties: white or off white crystalline powder. Salmon extract, soluble in hot water, ammonia water, dilute acid, difficult to dissolve in water, ethanol, insoluble in chloroform and ether

Purpose: biochemical research. It is a low molecular weight protein with strong alkalinity and strong positive charge. It can combine with strongly acidic heparin through ionic bond to form a stable complex, so that heparin loses anticoagulant activity (heparin is a sulfur lipid of mucopolysaccharide, which is strongly acidic and negatively charged, and its anticoagulant effect is related to the negative charge).

Storage: 2 ~ 8 ℃
