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 25 mM Trehalose. The lyophyllization buffer will contribute a significant amount of solids to the product. The product package size is based on protein content.

General description
Plasmin functions as a key enzyme of the fibrinolytic cascade, and is also important in inflammation processes. [1]
Application
Biochem/physiol Actions
It is inhibited by α 2-antiplasmin and its interaction with fibrin is blocked. [4] It digests the N-terminal region of the cytoplasmic protein αsynuclein preventing its uptake by surrounding cells. [5]
Plasmin exhibits preferential cleavage at the carboxyl side of lysine and arginine residues with higher selectivity than trypsin. Converts polymerized fibrin into soluble products.

Is the P1867-150UG product in Lys-Plasmin form or Glu-Plasmin form?
1 answer-
Both the Glu- and Lys- forms are assumed to be present in the product, as amino-terminal peptides are released from the native Glu-form to the new Lys-form by plasmin in vivo and during purification. No separation of the two forms is performed once purified plasminogen has been converted to plasmin.
