Yeast Nitrogen Base With Amino Acids is a highly-referenced medium containing essential vitamins, inorganic salts, trace elements, and specific amino acids (L-histidine, DL-methionine, and DL-tryptophan). It serves as a satisfactory nitrogen source for general yeast growth when supplemented with a carbohydrate source, typically glucose. The medium is widely used in molecular genetics, the preparation of imaging media, and studies involving synthetic dextrose (SD) medium to evaluate nitrogen source influences.
Advantages
- Comprehensive formulation providing nitrogen, vitamins, trace elements, and salts for robust yeast fermentation.
- Suitable for yeast classification based on the ability to utilize different carbon sources.
- Consistent performance in molecular biology applications, including ZYP-31 media preparation.
- High solubility (67 mg/ml in water) allowing for the preparation of 10x concentrated stock solutions.
