An ln vivo Assay for Biological Activity of Synthesized Recombinant Human Growth Hormone

In Vivo Bioassay of Recombinant Human Growth Hormone Synthesized in B. mori Pupae

The human growth hormone (hGH) has been expressed in prokaryotic expression system with low bioactivity previously. Then the effective B. mori baculovirus system was employed to express hGH identical to mature hGH successfully in larvae, but the expression level was still limited. In this work, the hGH was expressed in B. mori pupae by baculovirus system. Quantification of recombinant hGH prote...

Evaluation of Heat Induction Strategy for Recombinant Human Growth Hormone Expression in Fed-Batch Fermentation

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...

Purification of Large Quantities of Biologically Active Recombinant Human Growth Hormone

Production and purification of human growth hormone using a simple method was studied in two recombinantEscherichia coli, D7-5 and C27-2 strains. The r-hGH was expressed in the form of inclusion body in a batchfermentation process and purified to 99% purity using a procedure based on acid precipitation of the hostderived proteins and other impurities. The effect of the pH and ...
