说明书:

Staphylokinase
Staphylokinase Recombinant
Catalog No. ENZ-288

Synonyms:
Staphylokinase, SakSTAR, Neutral proteinase, Protease III, SAK.

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 15.5 kd.The Staphylokinase is purified by proprietary chromatographic techniques.

Source:
Escherichia Coli.

Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation:
The protein was lyophilized from a sterile solution containing 20mM phosphate buffer pH-7.

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.

Purity:
Greater than 97.0% as determined by:
(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 4600 IU/mg.

Amino acid sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be
Ser-Ser-Ser-Phe-Asp,
