WebIPTG induction. IPTG Induction and Extraction of Proteins from Bacteria Prepared by Swathi Arur and Sudhir Nayak Induction in bacteria can be performed using one of two basic methods. Fast induction does not work for all proteins and can give you suboptimal yields. Slow induction can enhance the solubility of some proteins. WebSep 1, 2010 · Additionally, Lee et al. (2007) have found that the presence of IPTG interferes with arabinose induction and that mutants of AraC can be isolated in which arabinose remains an inducer, but the interfering ability of IPTG is much reduced. These results show that AraC also binds IPTG.
