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. WebThe induction of T7 promoter with isopropyl-β-d-thiogalactopyranoside (IPTG) is widely used for expression of large quantities of proteins in Escherichia coli. It has been reported that …
