Cotton 100, ultra-filtered (UF)

Cotton 100, UF, is rich in nucleoside content and digested to enhance peptide content. It is processed to provide higher concentrations of vitamins, which can help maintain performance in mammalian and microbial processes.

Cotton 100, UF, is also part of the Peptone Preview Pak which contains:
• Cotton 200, UF—ultra-filtered and rich in nucleoside content, processed to enhance carbohydrate concentrations, which is important for some cell culture and microbial processes
• Wheat 100, UF—an ultra-filtered supplement and good source of glutamine, which makes it ideal for mammalian cell culture applications. It is digested for enhanced peptide content resulting in a low concentration of free amino acids and carbohydrates.
• Soy 100—a highly digested soy protein peptone that is high in nucleosides and free amino acid content. It has high concentrations of vitamins and carbohydrates and is recommend for a wide variety of processes.
• Pea 100, UF—an ultra-filtered peptone digested to enhance nucleoside and free amino acid content. The high total amino acid content and low carbohydrate content are similar to many high-performance animal origin peptones.
• Yeast 100—designed to enhance the content of vitamins and other key nutritional components found in yeast. It is intended for nutritional supplementation for mammalian, microbial, and insect cell culture.
