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.

WebWe developed a system in which IPTG as inducer was replaced by lactose which induces the tac-promoter with the same efficiency. In E. coli CW3011 (pOF1.0) lactose is utilized as inducer and carbon source even in the presence of glucose, presumably as a consequence of the overproduction of lac-permease.
