Lactalbumin Hydrolysate & Casein Peptones
While Nu-Tek BioSciences’ core competency is manufacturing animal free ingredients, a customer driven project yielded an enzymatically hydrolyzed whey and lactalbumin protein. With few viable alternatives on the market for Big Pharma, Lactalbumin Hydrolysate (LAH) remains a key component in serum free medias. Enhanced performance has been observed in classical culture media and insect cell culture media (sf9 & sf21).
Nu-Tek also distributes two proprietary blends of Casein products to help our customers to purchase multiple products from a single vendor. 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.
Lactalbumin Hydrolysate is produced by enzymatically hydrolyzing whey and lactalbumin protein. This highly hydrolyzed protein produces a peptone rich in amino acids and peptides with molecular weights less than 5,000 Daltons. View pdf here.
