Streptokinase Recombinant

Streptokinase is an extracellular metallo-enzymeproduced by beta-haemolytic streptococcusand is used as an effective and cheap clot-dissolving medicationin some cases of myocardial infarction(heart attack) and pulmonary embolism.
It belongs to a group of medications known as fibrinolytics, and works by activating plasminogenthrough cleavage to produce plasmin.
Description Streptokinase Recombinant produced in E.Coli is a non-glycosylated polypeptide chain containing 414 amino acids and having a molecular weight of 47kDa.
The Streptokinase is purified by proprietary chromatographic techniques.
Synonyms Streptokinase, SK.
Source Escherichia Coli.
Purity >96% as determined by SDS-PAGE and HPLC
Formulation Sterile Filtered White lyophilized (freeze-dried) powder.
Lyophilized from a 0.2µm filtered concentrated (1mg/ml) solution in PBS, pH 7.4.
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 specific biological activity measured by the ability of fibrin lysis in agarose plate was found to be 80000U/mg.
Solubility It is recommended to reconstitute the lyophilized Streptokinase in sterile 18M-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.
