In 1989, two undergraduate students at the Free University of Brussels were asked to test frozen blood serum from camels, and stumbled on a previously unknown kind of antibody. It was a miniaturized version of a human antibody, made up only of two heavy protein chains, rather than two light and two heavy chains. As they eventually reported, the antibodies` presence was confirmed not only in camels, but also in llamas and alpacas.
