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. WebIncubate at 37°C until OD 600 reaches 0.4–0.8. Induce with 4 or 40 µl of a 100 mM stock of IPTG (final concentration of 40 or 400 µM) and induce for 3 to 5 hours at 37°C. Check for expression either by Coomassie stained protein gel, Western Blot or activity assay. sly cooper thieves in time cast https://reneevaughn.com
