WebApr 3, 2024 · A Since you're using E. coli, you might consider a maltose binding protein tag to increase the solubility of your protein. The fact that the proteins are going into inclusion bodies suggests that your induction level is too high for the folding machinery in E. coli. You should troubleshoot and optimize for the best IPTG concentration. WebNov 3, 2014 · Heterologous expression of recombinant proteins in E. coli often results in the formation of insoluble and inactive protein aggregates, commonly referred to as inclusion bodies. To obtain the native (i.e., correctly folded) and hence active form of the protein from such aggregates, four steps are usually followed: (1) the cells are lysed, (2) the cell wall …
