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...
متن کاملTransformation and gene expression study of recombinant fish GnRH in E. coli BL21 in order to produce recombinant hormone
Gonadotropin releasing hormone (GnRH) is a neuropeptide known to regulate reproduction in vertebrates. Different analogues of synthetic GnRH are used to induce final sexual maturation in fish breeders. The purpose of this research was to evaluate the expression of recombinant GnRH (rGnRH) in Escherichia coli BL21 to produce recombinant hormone. In the present research, the sequence of DNA relat...
متن کاملOptimization and High Level Production of Recombinant Synthetic Streptokinase in E. coli Using Response Surface Methodology
Streptokinase (SK) is an extracellular protein comprising 414 amino acids with considerable clinical importance as a commonly used thrombolytic agent. Due to its wide spread application and clinical importance designing more efficient SK production platforms worth investigatinginvestigation. In this regard, a synthetic SK gene was optimized and cloned in to pET21b plasmid for periplasmic expres...
متن کاملReplication of plasmids from Staphylococcus aureus in Escherichia coli.
Plasmid pBR322 derives from plasmid ColE1 and does not replicate in Escherichia coli strains lacking DNA polymerase I. Hybrids between pBR322 and a plasmid isolated from Staphylococcus aureus, pC194, replicate in such E. coli strains, provided that the pC194 replication region is intact. Inactivation of the pBR322 replication region does not interfere with the replication of hybrids in E. coli....
