Auto Induction Media (AIM) was first formulated and developed by W. studier (Protein expression and purification 41: 207-234, 2005) to grow IPTG-inducible expression strains. The principle of AIM media is based on carbon sources in the medium that are metabolized differentially to promote high density cell growth and automatically induce protein expression from lac promoters. HiMedia offers a very specialized series of AIM media, with which a high density cell growth is followed by a spontaneous induction of protein expression and there is no need to monitor the cell density and there is no conventional induction with IPTG.
