General description

Sigma′s Yeast Transformation Kit contains all necessary reagents and controls for efficient transformation of yeast by the lithium acetate method.

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

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

Protocols

The selection of plasmids in yeast is based on the use of auxotrophic mutant strains, which cannot grow without a specific medium component (an amino acid, purine, or pyrimidine)

Yeasts are considered model systems for eukaryotic studies as they exhibit fast growth and have dispersed cells.

酵母は成長が速く、細胞が分散しているため、真核生物の研究に適したモデル生物と考えられています。

Articles

Genetic engineering enables large-scale expression and isolation of recombinant proteins for research purposes.

Transformation is the process by which exogenous DNA is introduced into a cell, resulting in a heritable change or genetic modification. This was first reported in Streptococcus pneumoniae by Griffith in 1928. Transforming principle of DNA was demonstrated by Avery et al. in 1944.
