Streptokinase is an extracellular metallo-enzyme produced by beta-haemolytic streptococcus and is used as an effective and cheap clot-dissolving medication in some cases of myocardial infarction (heart attack) and pulmonary embolism. It belongs to a group of medications known as fibrinolytics, and works by activating plasminogen through cleavage to produce plasmin.
Source:Recombinant protein corresponding to a non-glycosylated polypeptide chain containing 414aa from Streptokinase, expressed in E. coli.
Molecular Weight:~47kD
Biological Activity:One unit will liquefy a standard clot of fibrinogen, plasminogen and thrombin at pH 7.5 at 37°C in 10 min.
Storage and Stability:Lyophilized powder may be stored at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
