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).

Monoacylglycerol acyltransferases (MGATs) are predominantly associated with lipid absorption and resynthesis in the animal intestine where they catalyse the first step in the monoacylglycerol (MAG) pathway by acylating MAG to form diacylglycerol (DAG).

Yeast Transformation Introduction

Transformation introduces exogenous DNA into cells, a fundamental genetic modification process demonstrated in Streptococcus pneumoniae.

Protein Expression Systems

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

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)

Yeast Transformation Protocols

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

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