  • Gibson re-transformation: grow cultures
  • Re-transformation: 1x Gibson for pSB1A3 vector assemblies (3 & 4)


Gibson Re-transformation Results (1/06/13)

  • Number of colonies did not improve. Only 1 colony on hPCD + BL01 + V0120 plate
  • Streaks from yesterday: streak from plate 3 (hPCD + BL01 + pSB1A3 1xGibson) showed no color, whereas streak from plate 7 (hPCD + BL01 + pSB1A3 1/4x Gibson), showed RFP expression. The pSB1A3 template carries RFP.
  • Grow 2x 2 mL cultures from plate 3 streak to investigate whether an insert replaced RFP.
  • Do Zymo minipreps

Gibson Re-transformation

  1. hPCD + BL01 + pSB1A3 (#3), 1xGibson, 6.0 μL
  2. pSB1A3 (#4), 1xGibson, 6.0 μL
  • Add to 50 μL cells; ice/ 10 min.
  • Plate on 100 μg/mL amp LB agar
