Biological Activity Analysis of Native and Recombinant Streptokinase Using Clot Lysis and Chromogenic Substrate Assay
Determination of streptokinase activity is usually accomplished through two assay methods: a) Clot lysis, b) Chromogenic substrate assay. In this study the biological activity of two streptokinase products, namely Streptase®, which is a native product and Heberkinasa®, which is a recombinant product, was determined against the third international reference standard using the two forementioned a...

متن کاملAnalysis of five streptokinase formulations using the euglobulin lysis test and the plasminogen activation assay.
Streptokinase, a 47-kDa protein isolated and secreted by most group A, C and G ss-hemolytic streptococci, interacts with and activates human protein plasminogen to form an active complex capable of converting other plasminogen molecules to plasmin. Our objective was to compare five streptokinase formulations commercially available in Brazil in terms of their activity in the in vitro tests of eu...

متن کاملAn improved chromogenic substrate endotoxin assay for clinical use.
An improved quantitative assay for endotoxin in plasma was developed after evaluating three different chromogenic substrates and seven methods for removal of plasma inhibitors. Optimal storage conditions for plasma samples prior to assay were also determined. Using chromogenic substrate S2423 with plasma diluted 1/10 in water and heated to 75 degrees C for 5 min to remove inhibitors, a within-b...
