pGLO plasmid • Beta Lactamase • Ampicillin resistance • Green Fluorescent Protein (GFP) • Aequorea victoria jellyfish gene • araC regulator protein • Regulates GFP transcription

VERY IMPORTANT TO UNDERSTAND THIS SLIDE • Ampicillin (Amp) tests for the uptake of plasmid • Cells transformed with plasmid will GROW on Amp • Arabinose (Ara) removes repressor and express GFP • Cells transformed with plasmid and given Arabinose will GLOW on Amp + Ara
What will happen on these plates?Experiment 5.2 • Answer with die, grow or glow • Bacteria that were not transformed • LB • LB + Amp • LB + Amp + Ara • Bacteria that were transformed with pGLO plasmid. • LB • LB + Amp • LB + Amp + Ara
Experiment 7.3 – isolate GFP protein • What plates should we use? • LB only, LB + Amp or LB + Amp + Ara • What were these plates grown on?
What will happen on these plates?Experiment 5.1 • Answer with die, grow or glow • Bacteria that were not transformed • LB • LB + Amp • Bacteria that were transformed with S3 plasmid. • LB • LB + Amp
