Introduction
Staphylokinase (SAK) is a 136-amino acidenzymefrom Staphylococcus aureus. It is positively regulated by the "agr" gene regulator. It activates plasminogen, which in turn can degrade various host proteins during infection.
BP000851-ENZ-288: Recombinant Staphylokinase
Source: E. coli-derived.
N-terminal sequence analysis: Ser-Ser-Ser-Phe-Asp.
A non-glycosylated polypeptide chain containing 136 amino acids and having a molecular weight of 15.5 kd.
The biological activity measured by the ability of fibrin lysis in agarose plate was found to be 4600 IU/mg.
Purity > 97%, by RP-HPLC and SDS-PAGE.
Formulation: The protein was lyophilized from a sterile solution containing 20 mM phosphate buffer pH-7.
Reconstitution: It is recommended to reconstitute the lyophilized SAKin sterile 18 M?-cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
Shipping: The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70°C as supplied.
1 month, 2 to 8°C under sterile conditions after reconstitution.
3 months, -20 to -70°C under sterile conditions after reconstitution.
