- 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 (MV2, puro). 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
- See 03/19/13 for details about the oligos and reaction set-up
- Redo oligo annealing with 99.9 and 97.9°C starting temperatures...
