酵母トランスフェクションキット

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

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.

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).

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
