In this study Escherichia coli DE3 containing expression vector (pET21a) with cloned Persian sturgeon growth hormone (psGH) gene was grown in 10 mL LB broth on a 150 rpm shaker, at the temperature of 37 °C. At the late log phase (determined by OD standard curve) 100 &muL isopropyl &beta-D-1-thiogalactopyranoside (IPTG) was added for induction of GH synthesis. Samples were taken every 2 hours an...

background: b-thalassemia major is a serious medical problem. growth retardation is commonly seen in poly-transfused b- thalassemia patients. the exact mechanism of short stature in children with thalassemia major is not well understood, however, it is believed to be multi-factorial. objective: to study the growth state and its relationship to growth hormone (gh) deficiency in b-thalassemia pat...

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...
