Inclusion body refolding protocol
WebExpression 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. WebApr 8, 2024 · Protein Refolding Protocol The processing for inclusion bodies before refolding is important. Besides target proteins, inclusion bodies also contain some …
