Yeast Extract is a complex mixture of water-soluble vitamins, amino acids, peptides, and carbohydrates derived from the autolysis of yeast cells (Saccharomyces cerevisiae), used as a versatile nutrient supplement in microbiological and cell culture media.
Yeast Extract (Y1625) is a high-quality, dehydrated extract optimized for use in biotechnological applications and mammalian cell culture. It is produced by controlled autolysis of baker's yeast, followed by filtration and spray-drying to preserve essential growth factors. This product provides a rich source of B-complex vitamins, organic nitrogen, and minerals, making it an ideal supplement for promoting rapid growth in a wide variety of microorganisms and supporting high cell densities in bioreactor cultures. It is specifically tested for performance in cell culture systems to ensure the absence of inhibitory substances.
Advantages
- Cell Culture Tested: Verified for suitability as a supplement in mammalian cell culture media.
