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 کاملFluorescent assay for studying the substrate specificity of neuraminidase.
Toyopearl 650 M was purchased from Tosoh (Japan). The 10-~1 pipette tips with filter (cat. no. FI08-96R-I0) and thin-well 0.2-ml PCR microtubes (cat. no. 430-01XNBZ-Q) with caps were obtained from Porex. Black polystyrene 96-well microtiter plates were purchased from Nunc (Denmark, cat. no. 437111). Vibrio cholerae neuraminidase (3.2.1.18) was purchased from Sigma (USA). 3'SiaLac and 6'SiaLac w...

متن کاملApplications of a synthetic neuraminidase substrate.
A rapid and precise assay for neuraminidase using 2-(3'-methoxyphenyl)-N-acetyl-alpha-neuraminic acid (MPN) is described. It is proposed that this substrate be used for the standardization of activity of neuraminidases from viral, bacterial, and mammalian sources. MPN is also used as a chromogenic substrate to localize influenza and parainfluenza virus foci in tissue culture. This technique per...
