WebSpecifically, the influence of IPTG (isopropyl-beta-D-thiogalactoside) concentration, … WebWhen the OD600 reaches between 0.6-1.0 (approximately 2 hours), add IPTG to a final concentration of 500µM. This will induce the expression of the His6-GFP protein. Allow the culture to grow and express the GFP by shaking at 37°C for 16-24 hours. Note that in some cases, lowering the temperature after the induction may help proteins fold.
