WebFeb 19, 1999 · The presence of inclusion body impurities can affect the refolding yield of recombinant proteins, thus there is a need to purify inclusion bodies prior to refolding. We … 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.
Development of Solubilization and Refolding Buffers
Weband purify rhGM-CSF from inclusion bodies that generates milligram amounts of active protein from a single litre of E. coli. The refolding protocol described was also successfully used to refold Fab fragments of antibodies and thus may be used as a general refolding strategy for proteins forming inclusion bodies in E. coli such as many ... WebJan 20, 2024 · Inclusion bodies (IBs) are buildups of protein aggregates resulting from an unbalanced equilibrium between protein aggregation and refolding. IBs commonly form when bacteria, such as Escherichia coli, overexpress a foreign gene, leading to instability and aggregation of the produced polypeptide/protein [1, 2].There are multiple aspects … temperatura atual em biberach
