IPTG: Frequently Asked Questions and Protocols - AG Scientific
IPTG or Isopropyl β-D-1-thiogalactopyranoside is a chemical reagent that molecularly mimics allolactose, which removes a repressor from the lac operonto induce gene expression. Allolactose is an isomer of lactose, formed when lactose enters cells. It acts as an inducerto initiate the transcription of genes in the lac … See more The lac operon is a DNA region of Escherichia coli, containing three genes (lacZ, lacY, and lacA). The three genes, operated under a … See more IPTG induction is a method of regulating protein synthesis by triggering transcription of the lac operon. It requires two key players: See more There are two common protocols to induce proteins by IPTG: fast induction and slow induction. For fast induction, you can harvest your protein of interest at least 3-4 hours after IPTG induction. Whereas, for slow … See more A commonly used protocol would specify how much IPTG to add into growth medium containing the bacterial culture. For GoldBio’s protocols, use 1mM of IPTG in 1 ml of LB medium to make a final concentration of … See more WebOn the other hand, the induction of B-galactosidase responded differently when different carbohydrates were added (Fig. 2). The control culture containing only the IPTG and glycerol showed an early rapid induction, which eventually levelled. The culture in which galactose was added, at first, only had a slight decrease in induction.
