The Swedish biochemist Arne Wilhelm Kaurin Tiselius (1902-1971) was awarded the Nobel Prize for Chemistry for his researches on electrophoresis and adsorption analysis, especially for his discoveries concerning the nature of the serum proteins.

Arne Tiselius, son of Dr. Hans A. Tiselius, was born in Stockholm on Aug. 10, 1902. He studied chemistry at the University of Uppsala. Following his graduation in 1925, he became research assistant to the physical chemist Professor The Svedberg, the inventor of the ultracentrifuge. In 1925 Tiselius began to use electrophoretic analysis, long employed for proteins and enzymes. This method studies the migration of the components in a solution under the influence of an electric field, their moving boundaries being observed by fluorescent photography. Tiselius found the method unsatisfactory, and he developed the method of observing the components by ultraviolet-light photography, using quartz lenses and a special light filter. He considered his method very specific, but he...
