Calibration of IPTG-induced protein expression in E. coli

WebI usually induce at OD600 = 0.6, lower the temperature to 18 °C and express overnight (if I express at higher temperature, I have some issues with protein solubility). OK, so this approach works reasonably well, but I\’m looking for possible improvements regarding some tricky candidates. WebSample Induction Protocol (for reference only) ...
