Staphylokinase (SAK) is a 136aa enzyme from Staphylococcus aureus. It is positively regulated by the "agr" gene regulator. It activates plasminogen, which in turn can degrade various host proteins during infection.
Source:Recombinant protein corresponding to Staphylokinase, a non-glycosylated polypeptide chain containing 136aa, expressed in E. coli.
Molecular Weight:~15.5kD
Biological Activity:Measured by the ability of fibrin lysis in agarose plate and was found to be ~4600IU/mg.
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.
