WebIPTG is added to a final concentration of 0.4 mM for induction of protein expression. Before the addition of IPTG, an aliquot of cell culture should be removed and incubated separately as an uninduced control (sample 1, uninduced). Initially induction at 37°C for 2-4 hours can be tested for expression and solubility. WebInoculate starter culture at a 1:100 dilution into expression media containing antibiotic. Incubate at 37°C with shaking until OD 600 reaches 0.4–0.8. For most vector systems, induce with 40 or 400 μM IPTG and express protein for 3 hours at 37°C, 5 hours at 30°C or overnight at 16°C or 23°C. For large scale, inoculate 1 Liter of liquid ...

WebIPTG is a reagent which mimics the structure of allolactose, and can therefore bind to the lac repressor and prevent it from inhibiting gene expression. Once enough IPTG is added, the T7 gene is normally transcribed and so transcription of the gene of interest downstream of the T7 promoter also begins.
