Our Story

Nu-Tek BioSciences was founded on the belief that breakthrough biotechnology could be developed in a sustainable, ethical way by leveraging plant- and yeast-based cell culture nutrients. Our peptones and protein hydrolysates, used by industry-leading biotechnology and pharmaceutical companies, support a variety of applications ranging from mammalian cell culture to industrial fermentation. Our products are also leveraged in clinical nutrition and medicinal foods, such as allergen-free probiotics and other high-value nutritional products. With decades of experience and global reach, Nu-Tek BioSciences is your partner for animal-free yeast extracts and peptones.
