Yeast Peptones

Yeast Peptones are a solution built at the request of Big Pharma. Nu-Tek was tasked with creating a product which could be a consistently performing, viable alternative to yeastolate in both mammalian cell culture and insect cell culture. Yeast Peptone was developed for and has shown enhanced performance in CHO, Vero, NS0, sf9, and sf21 cell culture media.

The Nu-Tek customer base is global and includes the largest pharmaceutical supply and pharmaceutical manufacturing companies in the world. In a field of limited suppliers, Nu-Tek offers diversification, consistent and predictable performance, and long-term partnerships that address customer’s present and future needs.

Yeast Peptone NTB3-UF

NTB3-UF is a yeast hydrolysate of a selected strain of Saccharomyces cerevisae. The resulting yeast peptone is rich in peptides, vitamins, amino acids and other micronutrients. It is brilliantly clear and completely soluble in a 5% solution. NTB3-UF can be used by itself or in conjunction with other ingredients. Contact Us for more information.

Yeast Peptone NTB4-UF

NTB4-UF is a further derivative of the NTB3-UF and is a yeast hydrolysate of a selected strain of Saccharomyces cerevisae as well. The resulting yeast peptone is rich in peptides, vitamins, amino acids and other micronutrients. This material is ultra-filtered to further improve filterability. It also is brilliantly clear and completely soluble in a 5% solution. Similarly, NTB4-UF can be used by itself or in conjunction with other ingredients. Contact Us for more information.
