Web4. Post-transformation culture plates After transformation, the bacteria were grown in plates (plates A to D) containing IPTG, X-gal, and the antibiotic spectinomycin. PART 1: 1. What would have happened if we had cultured bacteria from any of the two starter plates in the post-transformation culture plates? 2. WebIsopropyl-β-D-thiogalactoside (IPTG) is commonly used in cloning procedures that require induction of β-galactosidase activity. It is used in conjunction with X-Gal or Bluo-Gal in blue-white selection of recombinant bacterial colonies that induce expression of the lac operon in Escherichia coli.
