Inclusion body e coli
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.

Isolation of properly folded, bioactive protein from IBs is a cumbersome task and most of the times results in poor recovery.
WebJul 27, 2024 · The single-chain insulin precursor molecules sequestered in E. coli inclusion bodies are mostly misfolded. The inclusion bodies are extracted from the cells, washed, and the precursor molecules are then solubilized. Production of proinsulin requires both peptide folding and concomitant formation of disulfide bonds.
