WebJan 28, 2024 · Expression of heterologous proteins in E. coli often leads to the formation of protein aggregates known as inclusion bodies (IBs). Inclusion body aggregates pose a major hurdle in the recovery of bioactive proteins from E. coli. Usage of strong denaturing buffers for solubilization of bacterial IBs results in poor recovery of bioactive protein. WebMar 1, 2000 · Recombinant human growth hormone (r-hGH) was expressed in Escherichia coli as inclusion bodies. In 10 h of fed-batch fermentation, 1.6 g/L of r-hGH was produced at a cell concentration of 25 g dry cell weight/L. Inclusion bodies from the cells were isolated and purified to homogeneity.
