Inclusion body refolding protocol
WebHere, we describe a single-step protocol used to purify and refold α-hemolysin that is produced as inclusion bodies in E. coli. Other methods of protein purification rely on multiple steps for the recovery of bioactive proteins from inclusion bodies, where the most important step is the refolding of the protein into a bioactive form. WebJul 29, 2024 · Escherichia coli has been most widely used for production of the recombinant proteins. Over-expression of the recombinant proteins is the mainspring of the inclusion bodies formation. The refolding of these proteins into bioactive forms is cumbersome and partly time-consuming. In the present study, we reviewed and discussed most issues …
