Staphylokinase Recombinant

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.
Synonyms	Staphylokinase, SakSTAR, Neutral proteinase, Protease III, SAK.
Source	Escherichia Coli.
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.
Purity	>96% as determined by SDS-PAGE and HPLC
Formulation	Sterile Filtered White lyophilized (freeze-dried) powder. The protein was lyophilized from a sterile solution containing 20mM phosphate buffer pH-7.
Stability	The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles.
Biological Activity	The biological activity measured by the ability of fibrin lysis in agarose plate was found to be 4600 IU/mg.
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.
Usage	LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes.
