WebApr 1, 2024 · Our novel integrative expression vectors based on Pgrac promoters could control the repression of protein production in the absence and the induction in the presence of an inducer, IPTG. The β-galactosidase (BgaB) protein levels were 9.0%, 15% and 30% of the total cellular protein in the B. subtilis strains carrying single cassettes with the ... WebPhase 5: Induction. Option 1: 37℃ Induction. Induce expression by adding IPTG to a final concentration of 0.5 mM after culture has reached OD600 0.5-0.6. Induce for 3-4 hours at 37℃ with shaking. Note: IPTG is a frozen solution in the -20℃ freezer. Option 2: Room Temp (20℃) Induction.
