Arne Wilhelm Kaurin Tiselius (10 August 1902 – 29 October 1971) was a Swedish biochemist who won the Nobel Prize in Chemistry in 1948 "for his research on electrophoresis and adsorption analysis, especially for his discoveries concerning the complex nature of the serum proteins.
Tiselius became a research assistant at Theodor Svedberg's laboratory in 1925 and obtained his doctoral degree in 1930 on the moving-boundary method of studying the electrophoresis of proteins.
From then to 1935 he published a number of papers on diffusion and adsorption in naturally occurring base-exchanging zeolites, and these studies continued during a year's visit to Hugh Stott Taylor's laboratory in Princeton University with support of a Rockefeller Foundation fellowship.
Tiselius took an active part in the reorganization of scientific research in Sweden in the years following World War II, and was President of the International Union of Pure and Applied Chemistry 1951–1955.
