Sigma has not evaluated the activity of this enzyme in I.U., nor do we have a conversion factor.
What is the molecular weight of Product P1867, Plasmin from human plasma?
The molecular weight of this dimeric protein was reported to be 75,400 Daltons. Reference is: The Plasma Proteins, Volume 1, 2nd ed., Putnam, F.W., ed., p. 66 (1975).
What is Product P1867, Plasmin from human plasma, soluble in?
It is soluble in water.
Can you provide a method of production for Product P1867 - Plasmin?
Product P1867 - Plasmin from human plasma is from an outside supplier and the manufacturing process is considered proprietary. The product is activated with Streptokinase and this enzyme is removed in the final steps of the purification. The product is >95% by SDS PAGE. The product is >3% protein (the exact value will be on the lot specific Certificate of Analysis). This material is lyophilized from 20 mM sodium phosphate (pH 7.4), containing 10 mg/ml D-mannitol and 10 mg/ml NaCl. The lyophyllization buffer will contribute a significant amount of solids to the product. The product package size is based on protein content.
