A new animal-free IPTG (Isopropyl-Beta-D-galactopyranoside) is now available from BioVectra. IPTG is commonly used as a lac-operon inducer, which irreversibly binds the lac repressor. The lac operon is a commonly used genetic element in transcription research, for the detection of gene insertion. IPTG binds to a specific site on the lac repressor, causing a conformational change which results in its dissociation from the lac operon. IPTG is often ultimately used in the large-scale expression of expressed compounds.
