·DH5alpha + pCS26-pac
·DH5alpha:RP4 + pCS26-pac
Yeast Shuttle Plasmid
- PEG, LiAc, TE combination plate buffer was made. - Single stranded carrier DNA was denatured in boiling water for 3 minutes, then placed on ice. - 1200 uL of yeast in liquid YEPD media was separated into two Eppendorf tubes. These were centrifuged and pelleted, then the supernatant was decanted. - 5 uL of carrier DNA was pipetted into each tube of pelleted yeast, then 10 uL of pAC88 and 10 uL of sterile water was pipetted into the experimental and control tubes, respectively. - The mixture was vortexed then centrifuged for 10 seconds to repellet the cells. - The supernatant was poured off, then 100 uL aliquots of plate buffer was used to resuspend the cells. - The mixture was vortexed again, then centrigued for another 10 seconds. - Finally, the supernatant was poured off, and 5 uL of DMOS was added. - The two mixtures were plated on two leucine-deficient plates then placed in an incubator at 30 degrees Celsius to grow for the weekend.
