The interaction of human growth hormone with human lymphocytes from an established culture (IM-9) was studied using lz51-human growth hormone. The binding of l*51human growth hormone was rapid; with human growth hormone at 0.1 no a steady state was observed in 90 min at 30”. Bound labeled human growth hormone was dissociated rapidly by addition of excess unlabeled human growth hormone. Binding ...
Growth hormone secretion is classically modulated by two hypothalamic hormones, growth hormone-releasing hormone and somatostatin. A third pathway was proposed in the last decade, which involves the growth hormone secretagogues. Ghrelin is a novel acylated peptide which is produced mainly by the stomach. It is also synthesized in the hypothalamus and is present in several other tissues. This en...
for high-throughput production of recombinant protein in escherichia coli ( e. coli ), besides important parameters such as efficient vector with strong promoter and compatible host, other important issues including codon usage, rare codons, and gc content specially at n-terminal region should be considered. in the current study, the effect of decreasing the percentage of gc nucleotides and opt...
the interaction of hgh with some metal ions ( ) at 27°c in nac1 solution, 50 mm was studied using isothermal titration calorimetry. there is a set of three identical and non-interacting binding sites for binding of all these metal ions, expect . the intrinsic association equilibrium constants () are not very different for and , and also their molar enthalpies of binding (kj/mol for and kj/mo...
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...
