Product Information
Description: Yeast Nitrogen Base Without Amino Acids and Ammonium Sulfate is recommended to use for classifying yeasts based on their carbon and nitrogen requirements. The medium contains all essential nutrients required for the growth of yeasts except amino acids, histidine, methionine and tryptophan, and also ammonium sulphate. The addition of nitrogen and carbon sources is required.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
