Other Notes

The Yeast Transformation Kit contains:
  • Transformation Buffer; 100 ml; 100 mM lithium acetate, 10 mM Tris HCl, pH 7.6, and 1 mM EDTA
  • Plate Buffer; 100 ml; 40% PEG, 100 mM lithium acetate, 10 mM Tris HCl, pH 7.5, 1 mM EDTA
  • Deoxyribonucleic acid from salmon teste, 10 mg/ml; 2 x 1 ml
  • Control Yeast Plasmid DNA pRS316 carrying the ura gene; 10 μg
  • Yeast Synthetic Drop-out Medium Supplement Without Uracil; 1 g

Application

Suitable for transformation of any strain of yeast. Convenient, flexible and sensitive, positive transformants can be obtained with as little as 10 ng of DNA; the optimum efficiency is in the 0.1- 3 μg range.

Biochem/physiol Actions

Transformation with a plasmid complementing the mutated gene enables the transformant to grow on medium lacking the required component. Yeast cells are made competent for transformation by incubation in a buffered lithium acetate solution. Transformation is then carried out by incubating the cells together with transforming DNA and carrier DNA in a solution containing polyethylene glycol (PEG).

Features and Benefits

  • Easy and ready-to-use
  • Requires as little as 10 ng of plasmid DNA
  • Flexibility for any strain of yeast
  • Sufficient for over 100 standard transformations

Type II topoisomerases catalyze essential DNA transactions and are proven drug targets. Drug discrimination by prokaryotic and eukaryotic topoisomerases is vital to therapeutic utility, but is poorly understood.
