Background: The production of recombinant human growth hormone is usually problematic in Escherichia coli, and achieving higher functional protein yields economically important. Objectives: In this study, the chromosomal expression (hGH) araBAD operon was investigated using Rosetta-gami BL21 (DE3) competent cells under regulation arabinose T7 promoters inducer IPTG, respectively. Subsequently, ...
