Newest EcoRI/BamHI Transfer method (7/31/08)

Digestion:

  • 0.5ul plasmid in entry vector
  • 0.5ul EcoRI
  • 0.5ul BamHI
  • 1ul NEB2 + ATP buffer
  • 7.5ul of water
  • incubate the digestion for 1hr. in the thermocycler, and 20 min for heat kill.

No purification step.

Ligation:

  • 1ul of dilute assembly vector (or 0.5ul if undiluted)
  • 0.5ul ligase

Transform. (same as usual)

Transfers from Miniprepped DNA

(already in correct vectors - transfers into L/R cells)

In 0.5 ml tube, combine:

  • 1ul plasmid dna
  • 30ul of cells (L/R) + 30 KCM (no water)

Take the reaction, and:

  • sit in ice for 10 min
  • heat shock for 90 sec
  • sit another 2 min ice

Then, incubate your tubes for 5 minutes (No rescuing is necessary)

Next, prepare plates (double antibiotics) and tubes with media (LB + antibiotics)

  • Take 15ul of rxn. Spot it onto a plate (no spreading required)
  • Take the remaining 15ul into a pipette tip. Drop the entire tip into your tube of media.
  • Let plates and tubes sit overnight.
  • Miniprep the next day.


1-2-3 Assembly

Set up the digestion:

  • 1uL lefty plasmid(methylated)
  • 1uL righty plasmid (methylated)
  • 1uL NEB2+ATP
  • 0.3 uL XhoI
  • 0.3 uL BglII
  • 0.3 uL BamHI
  • 6.1uL Water

Heat kill at 65 for 20 min

Add 0.3uL Ligase

Transform, rescue, plate on dual antibiotic plates
