Transgenic non-human mammals producing oligosaccharides and glycoconjugates
First Claim
1. A transgenic non-human mammal, whose genome comprises a transgene construct comprising a DNA sequence encoding human α
- -1,2-fucosyltransferase operatively linked to a mammary gland specific promoter, wherein expression of the DNA sequence results in the production of detectable levels of 2'"'"'-fucosyl-lactose in the milk of said mammal.

Abstract
The invention relates to transgenic non-human mammals characterized in that the genome of said mammals contain at least one heterologous gene encoding for the production of heterologous catalytic entity selected from the group consisting of enzymes and antibodies, and wherein said catalytic entity produces a second heterologous product in the milk of said mammal. Especially useful in the practice of the invention are human glycosyltransferases and transgenic sheep, goats and cows. The heterologous product includes oligosaccharides and glycoconjugates. Specifically exemplified, is the production of 2'"'"'-fucosyl-lactose in the milk of transgenic mice which contain and express a transgene encoding α-1,2-fucosyltransferase operatively linked to a mammary gland specific promoter.
