Variables influencing the clot lysis assay of streptokinase.

Abstract:

:Clot lysis induced by streptokinase has been studied and the influences of pH and the concentrations of plasminogen, fibrinogen and buffer composition investigated. Variations in the concentrations of plasminogen strongly effect the SK apparent activity, maxima being obtained at different plasminogen concentrations linearly dependent on the concentration of fibrinogen. Buffer composition and pH also effect the apparent activity and the maxima obtained are dependent on the fibrinogen concentration. Analytical conditions are discussed and suitable sample and reagent volumes, as well as concentrations of the reactants and buffer environment, are suggested.
