Yeast Auxotrophic Selection: Supports selection of MET-marker strains and plasmids in Saccharomyces cerevisiae using methionine dropout with purine/pyrimidine supplementation.

Yeast Transformation and Screening: Used for plating and screening transformants requiring methionine selection while minimizing background from adenine, guanine, and uracil auxotrophies.

CRISPR/Cas9 and Genome Editing: Enables selection of edited yeast clones using MET-based markers in a defined medium.

Sulfur/Methionine Metabolism Studies: Facilitates controlled studies of methionine biosynthesis and MET regulon induction in defined conditions.

Recombinant Protein Expression in Yeast: Provides a consistent, defined medium for expression and strain screening under methionine-limited conditions.

Growth Kinetics and Phenotyping: Used for growth curves and fitness assays in minimal, methionine-controlled environments.

Amino Acid Transport Assays: Supports uptake and transporter characterization for methionine in yeast.

Synthetic Biology and Circuit Testing: Maintains defined auxotrophic selection for yeast chassis during design-build-test cycles.
