(b)The pH6GFPuv is purified from overnight culture of the
pGFPuv inE. coli strain TG1 in 3 mL of Luria broth with
3mL of 100 mg/mL ampicillin. Cells are harvested by
centrifugation at 11,000 ×g 1 min and used a NucleoSpin®
Plasmid kit to purify the plasmid. Plasmid DNA is eluted
in 50mL of Buffer AE (elution buffer) and diluted to get
a concentration of 2 ng/mL before use.
