Multiporator / Electroporator 2510 Transformation Protocol Protocol No. 4308 915.531 12/2001 Microorganism Saccharomyces cerevisiae Cell type Yeast Molecules injected Plasmid DNA Growth medium YEPD (1% yeast extract, 2% bactopeptone, 2% dextrose) Washing solution Ice-cold, sterile water; ice-cold 1 M sorbitol Electroporation solution Ice-cold 1 M sorbitol Outgrowth medium 1 M sorbitol Cuvette 2 mm gap width Reference Dr. Robert Sclafani University of Colorado Health Science Center Denver, CO USA Making electrocompetent cells:

1. Inoculate 500 ml YEPD with an aliquot of an overnight culture or a colony from a plate and grow to an O.D.600 of 1.3-1.5 (about 1 x 108 cells/ml). 2. Harvest by centrifugation at 4,000 x g for 5 min. at 4 C. 3. Wash in 500 ml ice-cold sterile water, centrifuge (4,000 x g, 5 min., at 4 C), repeat washing step with 250 ml water. 4. Resuspend in 20 ml ice-cold sorbitol and c entrifuge as above. Resuspend in 0.5 ml of 1 M sorbitol to a final volume of 1.0 to 1.5 ml, keep on ice.

Electroporation of cells:

  1. Add <5 l (0.1 g) DNA to 65 l of electrocompetent cells. Homogenize by gently mixing with pipette several times. Incubate 5 min on ice. Transfer mixture into a prechilled cuvette.
  2. Wipe moisture from the cuvette and insert the cuvette into the device.
  3. Electroporation:

    Mode Prokaryotes O Voltage (V) 1,500 V Time constant (T) 5 ms
  4. Immediately add 1 ml of cold sorbitol. Plate various aliquots onto selective plates containing 1 M sorbitol.
Expected results: Transformation efficiency up to 104 to 105 transformants/g of DNA. Note: It is possible to scale this protocol down by starting with a culture volume of 50 ml.
