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.
Description
Staphylokinase Recombinant produced in E.Coli is a non-glycosylated polypeptide chain containing 136 amino acids and having a molecular weight of 16kDa.
The Staphylokinase is purified by proprietary chromatographic techniques.
The Staphylokinase is purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.
Solubility
It is recommended to reconstitute the lyophilized SAKin sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized SAK although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution SAK should be stored at 4°C between 2-7 days and for future use below -18°C.
Please prevent freeze-thaw cycles.
Please prevent freeze-thaw cycles.
Purity
Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Biological Activity
The biological activity measured by the ability of fibrin lysis in agarose plate was found to be 50,000IU/mg.
