Anthony John Clark

Who was Anthony John Clark?

Anthony John Clark was the head of the Roslin Institute.

English molecular biologist who was a founder of applying molecular technology to farm animals. In 1985, he began work in genetic modification to produce a sheep giving milk with human proteins. He was successful within five years. Tracy, the result of five year's work, produced 35g of the alpha-1-antitrypsin in each liter of her milk. During the 1990s, Clark continued to develop transgenic techniques on large animals. With his colleagues, he produced a sheep from which a prion protein gene had been removed. Clark's work set the stage for Ian Wilmut's team at Roslin to clone a sheep, Dolly, the result of transplanted DNA of an adult sheep to an unfertilized egg cell.
