In this experiment, your students can see a blue color change in transformed cells due to the switching on of a gene. The pGAL plasmid gives them a blue color due to the production of the ß-galactosidase protein by the lacZ gene. IPTG is not required in this experiment since pGAL contains the complete lacZ gene. For 10 Lab Groups (2-4 Students per Group). Kit includes: instructions, BactoBeads, plasmid DNA, buffer, media, ampicillin, X-Gal, ReadyPour agar, petri dishes, sterile pipettes, loops and microtubes. You need: 37ºC incubation oven, water bath, microwave or hot plate.
