Name: Arne Wilhelm Kaurin Tiselius
Country: Sweden
Date of Bitrh: August 10, 1902
Birth Place: Stockholm
Date of Death: October 29, 1971 (Uppsala, Sweden)
Subject of Study: Chromatography, Electrophoresis and Protein
Noble Prize Year: Nobel Prize for Chemistry in 1948 for his work on electrophoresis and adsorption analysis.
About: Arne Tiselius was a Swedish biochemist, As an assistant to Svedberg at the University of Uppsala (1925–32), Tiselius developed the use of electrophoresis for the delicate task of separating proteins in suspension on the basis of their electrical charge. For this work, he was awarded his doctorate in 1930.

After lecturing at Uppsala, he conducted research at the Institute for Advanced Study at Princeton (1934–35). Returning to Uppsala in 1937, he became a professor of biochemistry and was provided with a newly built institute to house his department. He used electrophoretic methods to separate the chemically similar proteins of blood serum, an achievement that was especially cited in the Nobel award. In 1940, he began research into the separation of proteins and other substances by adsorption chromatography. Tiselius was chairman of the Swedish Natural Science Research Council (1946–50) and then vice president (1947–60) and president (1960–64) of the Nobel Foundation.
