Streptokinase Recombinant ( Streptokinase )

Data sheet

Formulation

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

Solubility

It is recommended to reconstitute the lyophilized Streptokinase in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

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

Description

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.

Protein Background

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 m

Expression host

Escherichia Coli.

Synonyms

Streptokinase, SK.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

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
