The Over-Expression of Biologically Active Human Growth Hormone in a T5-Based System in Escherichia coli, Studying Temperature Effect

We studied the expression of human growth hormone (hGH) in E. coli under a bacteriophage T5-base promoter in a pQE30 expression vector. For an efficient expression of hGH cDNA, a number of codons at the hGH N-terminal coding region were altered based on the E. coli major codons. An over-expression of hGH in the bacteria, carrying the recombinant plasmids, was observed at 37°C in the presence of...

Using L-arabinose for Production of Human Growth Hormone in Escherichia coli, Studying the Processing of gIII::hGH Precursor

Over Expression of Biologically Active Interferon Beta Using Synthetic Gene in E. coli

In this study, our previously reported novel synthetic gene encoding 166 residues of interferon-? was used for an efficient expression of IFN-?. The synthetic gene was cloned into pET21a expression vector and transferred into E. coli. Recombinant protein was over-expressed in the E. coli. Identity of the recombinant protein was confirmed by western blot analysis. The recombinant protein was bio...

CONSTRUCTION OF RECOMBINANT PLASMIDS FOR PERIPLASMIC EXPRESSION OF HUMAN GROWTH HORMONE IN ESCHERICHIA COLI UNDER T7 AND LAC PROMOTERS

In order to study the periplasmic expression of human growth hormone (hGH) in Escherichia coli, the related cDNA was inserted in two expression plasmids carrying pelB signal peptide, one with lac bacterial promoter and the other with a bacteriophage T7-based promoter. The recombinant plasmids were moved to TG1 and BL21 strains of E. coli, respectively. To induce the expression systems, IPTG and...

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 ...
