Description

Application

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.

Components

The supplements contain all of the following components except as indicated:
Amino acids: All standard amino acids except for histidine. All the amino acids are present at a concentration of 76 mg/lL except for leucine, which is present at 380 mg/L.
Other nutrients: Adenine (18 mg/L), inositol (76 mg/L), uracil (76 mg/L), p-aminobenzoic acid (8 mg/L).
