CAS: 9009-65-8, protamine sulfate, protamine, protamine, protamine sulfate, Protamine sulfate
Potency: Based on dry product, the anticoagulant effect of heparin neutralized per 1 mg protamine sulfate should not be less than 100 units, and its potency should be 90 to 110% of the marked amount
Nitrogen content: 21 ～ 25%
Loss on drying: ≤7%
English name: Protamine sulfate; Salmine sulfate
Other names: Protamine; Protamine; Protamine Sulfate
CAS number: 9009-65-8 or 53597-25-4
Molecular weight: 5000 ～ 10000
Level: BR
Identification: Qualified traits: white or off-white crystalline powder. Salmon extract, soluble in hot water, ammonia, dilute acid, insoluble in water, ethanol, insoluble in chloroform and ether. Uses: biochemical research. It is a low-molecular-weight protein with strong basicity and a strong positive charge. It can combine with strongly acidic heparin to form a stable complex through ionic bonds, so that heparin loses anticoagulant activity (heparin is a sulfide of mucopolysaccharides, which has a strong acidic negative charge, and its anticoagulant effect is related to the negative charge) .
Storage: 2 ～ 8 ℃
