  • Publication number: 20220411840
    Abstract: The invention is directed to compositions and methods for enzymatic template-free synthesis of polynucleotides wherein different terminal deoxynucleotidyl transferase (TdT) variants are used to incorporate different 3?-O-reversibly blocked deoxynucleoside triphosphates (dNTPs) into a growing chain. In part, the invention is a recognition and appreciation that different TdT variants can be engineered to preferentially incorporate specific dNTPs with higher efficiency than a single “general purpose” TdT variant used to incorporate all four 3-O-reversibly blocked dNTPs.

  • Patent number: 11173171
    Abstract: A mixture of human milk oligosaccharides that consists essentially of 3?-O-sialyllactose, a component A which is either 3-O-fucosyllactose or lacto-N-tetraose, a component B which is 3-0-fucosyl-3?-O-sialyllactose when component A is 3-O-fucosyllactose and sialyllacto-N-tetraose a, when component A is lacto-N-tetraose and optionally lactose as a fourth component. The mixtures are made by treating 3?-O-sialyllactose and component A with an ?2,3-transsialidase.
