Human growth hormone-anti-(growth hormone) immunoprecipitates in the presence of dextrans.

RT-PCR MEDIATED CLONING OF HUMAN GROWTH HORMONE GENE AND I TS EXPRESSION IN E. coli

Human growth hormone (hGH) genomic sequence containing 5 exons and 4 introns was cloned in pcDNA-3 and the constructed plasmid was subsequently used for transfection ofNlli-3T3 cell line using lipofection technique. Expression of hGH in stably transfected cells was assayed using ELISA. Total RNA was extracted from transfected cells and hGH cDNA was amplified by RT-PCR using specific primers...

Transient Expression of Human Growth Hormone in Potato (Solanum tuberosum), Tobacco (Nicotiana tobacum) and Lettuce (Lactuca sativa) Leaves by Agroinfiltration

Using agro-infiltration technique, we have transiently expressed human Growth Hormone (hGH) in tobacco(Nicotiana tobacum), potato (Solanum tuberosum) and lettuce (Lactuca sativa) leaves. Out of three differentinoculation times used for infiltration in our study, it was seen that highest level of hGH expression wasachieved when leaves were infiltrated for 35 min. The presence o...

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

The relationship between growth hormone polymorphism and growth hormone receptor genes with milk yield and reproductive performance in Holstein dairy cows

The aim of this study was to investigate the potential association between growth hormone GH/AluI and growth hormone receptor GHR/AluI polymorphisms with milk yield and reproductive performances in Holstein dairy cows in Iran. Blood samples of 150 Holstein cows were collected and their genomic DNA was extracted using Gene-Fanavaran DNA extracting kit. Fragments of the 428 bp of exon 5 growth ho...
