WebApr 7, 2024 · For example, for pET, the IPTG-induced recombinant protein expression requires the T7 RNA polymerase to be expressed in the host strain, which is not present in Stbl3. As such, bacterial expression vectors typically require transferring the plasmid into an appropriate host strain such as BL21 (DE3) for proper induction. WebOne of the most popular E. coli strains for recombinant protein production is E. coli BL21(DE3) which is usually used in combination with the pET expression system. However, it is well known that induction by isopropyl β-D-1-thiogalactopyranoside (IPTG) stresses the cells and can lead to the formation of insoluble inclusion bodies.
