Application

Yeast Synthetic Drop-out Medium Supplements, without histidine, leucine, tryptophan, and adenine has been used in yeast two-hybrid screening.
The selection of plasmids in yeast is based on the use of auxotrophic mutant strains that cannot grow without a specific media component (an amino acid, purine or pyrimidine). Transformation with a plasmid containing the mutated gene enables the transformant to grow on a medium lacking the required component. Sigma′s Yeast Synthetic Drop-Out Media Supplements create a richer medium for better yield and growth rate, and increase the probability of successful transformations when screening libraries or performing gene knock-outs.

Other Notes

Mixtures of amino acids and other nutrients to be added to Yeast Nitrogen Base Without Amino Acids.

Preparation Note

Introduction to Yeast Media

Technical Article on yeast media. Yeasts are eukaryotic microorganisms whose genomes have been comprehensively studied and some have been sequenced.

Protocols

Yeast Drop Out

Yeast Drop Out Bulletin. 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). Transformation with a plasmid containing the mutated gene enables the transformant to grow on a medium lacking the required component. Although yeast can grow on a synthetic medium without any amino acids, better yield and growth rate can be achieved on richer media.

Yeast Growth Protocols

Yeasts are considered model systems for eukaryotic studies as they exhibit fast growth and have dispersed cells. Yeast cultures can be grown, maintained, and stored in liquid media or on agar plates using techniques similar to those for bacterial cultures.

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