Beschreibung

General description

Research area: Cell Signaling

Streptokinase is an extracellular enzyme, a single-chain polypeptide produced by several strains of β-hemolytic Streptococci. It is composed of multiple structural domains like α-, β-, and γ-domains that are involved in various functions.

Application

Streptokinase C from Streptococcus sp. has been used to quantitate the survival of Staphylococcus aureus in whole human blood.[1]

Biochem/physiol Actions

Streptokinase shows fibrinolytic activity by triggering the circulatory plasminogen either via a fibrin-dependent or fibrin-independent mechanism. Streptokinase has been studied majorly in terms of its therapeutic efficacy and treating myocardial infarction to dissolve clots.

Physical form

Lyophilized powder containing approx. 50% bovine serum albumin (total protein by biuret) with sodium glutamate.

Other Notes

One unit will liquify a standard clot of fibrinogen, plasminogen, and thrombin at pH 7.5 at 37 °C in 10 min.
