Nu-Tek Yeast Extract 903

This yeast‑based extract is formulated to deliver a robust blend of peptides, vitamins, amino acids, and essential micronutrients that support mammalian cell culture and microbial vaccine manufacturing. Derived from Saccharomyces cerevisiae, it dissolves fully in a 5% solution and produces a brilliantly clear appearance, ensuring compatibility with demanding bioprocess workflows. Its nutrient-rich composition makes it suitable for use alone or alongside other media components, offering flexibility across production environments. Quality characteristics—including moisture content, nitrogen levels, amino nitrogen percentage, pH range, AN/TN ratio, and microbial specifications—are strictly controlled to ensure consistency and reproducibility. The material maintains low bioburden, with limits on standard plate count, coliforms, yeast and mold, and confirmed negative results for Salmonella, supporting use in sensitive applications. Packaged in 25 kg polyethylene bags within protective containers, it remains stable in cool, dry storage for up to three years, ensuring long-term reliability.
