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.

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

Components

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

Principle

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).

Introduction to Yeast Transformation

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.

Protein Expression Systems

The development of genetic engineering and cloning has opened many possibilities of expression and isolation of heterologous proteins for research purposes. Considerable advances in technology have enabled expression and isolation of recombinant proteins in large scale.

Protocols

Yeast Transformation Kit

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)

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
