Streptokinase Recombinant Protein

Source : Escherichia Coli. Streptokinase Recombinant produced in E.Coli is a non-glycosylated polypeptide chain containing 414 amino acids and having a molecular weight of 47.3kDa.The Streptokinase is purified by proprietary chromatographic techniques. 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.

Product Specifications

Product Name Alternative

Streptokinase||SK.

Purification

Greater than 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.

Components

Lyophilized from a 0.2μm filtered concentrated (1mg/mL) solution in PBS, pH 7.4.

Storage Conditions

Lyophilized Streptokinase although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Streptokinase should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles.

Applications Notes

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. The specific biological activity measured by the ability of fibrin lysis in agarose plate was found to be 80000U/mg.
