  • Golden gate: PCR parts, complete protocol for Brady's construct
  • Gibson: PCR parts; waiting on BsmBI from NEB


Gibson Assembly

  4. BL01, hPCD-BL01 fwd (BL8) / BL01-BBS rev (BL10)
Reagent Volume Expected:
G1. V0120 = 3200
G2. pSB1A3 = 2000
G3. hPCD = 186
G4. BL01 = 2520 		Hover name

  50 μL
  • 95°C, 3 min.
  • [95°C, 30 sec.; 57°C, 30 sec.; 72°C, 2 min.] x 30
  • 72°C, 3 min.
  • 4°C, ∞

Measure DNA Concentrations

Sample OD 260 260/ 280 ng/μL
G1 V0120 0.108 1.801 108.375
G2 pSB1A3 0.101 1.849 100.553
G3 hPCD 0.034 1.876 33.586
G4 BL01 0.113 1.828 112.79


Reaction set-up

  • Use 0.2 - 0.5 pmol, per NEB's suggestion, [1]
  • pmols = ng x 1000 / bp x 650 daltons; ng = (pmols x bp x 650 daltons) / 1000
  • Total volume of DNA = 5.0 μL max

1. hPCD + BL01 + V0120

  • vector V0120, 0.1 pmol = 208 ng = 1.9 μL (use 1.4 μL)
  • 2:1 insert hPCD, 0.2 pmol = 24 ng = 0.7 μL
  • 2:1 insert BL01, 0.2 pmol = 328 ng = 2.9 μL

2. hPCD + BL01 + V0120

  • vector pSB1A3, 0.1 pmol = 130 ng = 1.3 μL
  • 2:1 insert hPCD, 0.2 pmol = 24 ng = 0.7 μL (use 0.8 μL)
  • 2:1 insert BL01, 0.2 pmol = 328 ng = 2.9 μL

Transformation

  • (1) Transform: add 2.0 μL to 40 μL DH5α-Turbo; ice/5 min.; plate on warm 100 μg/mL amp. agar
  • (2) NEB also suggests diluting 5.0 μL of the Gibson reaction into 15.0 μL dH2O (20.0 total vol.), and using 2.0 μL diluted DNA, [2]
  • Test both methods (8 plates total)
    • Plates 1-4, method 1

Golden Gate Assembly

  • Try new protocol from Dave Savage
