Edinburgh Roslin Institute chicken

Dr Helen Sang holds a chicken during a press conference at the Roslin Institute, Edinburgh. Sang announced a joint project with United States company Viragen to begin a programme to develop an antibody to skin cancer to be produced in a chicken egg. *...The Roslin Institute has produced transgenic chickens before but this will be the first time that this technology has been applied to produce therapeutic drugs. Dr Sang, who is leading the research team, said the significance of using chickens' eggs to produce the protein drugs is that it promises much higher volumes, faster production times, unlimited capacity and lower costs.
