  • Oligo annealing, round 2
  • Assembly: annealed part into MV2



Assemblies

  • New strategy for mammalian vector:
    • Insert K-XbaI-NLS-6his-stop into the puro vector that has a deleted promoter. This way, the vector can be customized to carry different promoters.
    • Insertion of the ds oligo should destroy the vector's XbaI site
    • Will need to check inserts for copy number and orientation


  • Oligo annealing
  • Redo oligo annealing with 99.9 and 97.9°C starting temperatures...
  • Previous Thermal cycling (3/19/13)
    • 99.9, 10 min.
    • [99.9, 1 min., -2°C; 90.0, 1 min., -2°C] x35
    • 25°C, ∞
    • Labeled tubes A1, A2; Stored on bench o/n
  • New Thermal cycling (3/20/13)
    • 99.9, 10 min.
    • [99.9, 1 min., -2°C; 97.9, 1 min., -2°C] x36
    • 25°C, ∞
