E. coli fermentation unit. Researcher injecting a 1-litre laboratory fermentor with a starter strain of Escherichia coli bacteria (upper left). These will have been genetically modified to produce antibodies. Antibodies are proteins that are part of the human body's immune system. The fermentation unit will provide heat and nutrients for the growth of the bacteria. Photographed at a Celltech research laboratory, UK.
