Tiselius, Arne

(är`nə tēsā`lyəs), 1902–71, Swedish biochemist. He received the 1948 Nobel Prize in Chemistry for developing new methods of separating and detecting colloids. One system (electro-phoresis) employs an electrical apparatus (Tiselius apparatus) for the separation of heavy molecules in solution; the other is a method of adsorption analysis that permits the differentiation and separation of substances, e.g., proteins, sugars, salts, and acids. Tiselius isolated the virus of mouse paralysis and developed synthetic blood plasma. In 1925 he joined the faculty of the Univ. of Uppsala; he did research at the Institute for Advanced Studies at Princeton in 1934–35 and at the Rockefeller Institute, New York City, in 1939.

Tiselius, Arne

 

Born Aug. 10, 1902, in Stockholm; died Oct. 29, 1971, in Uppsala. Swedish biochemist. Member and president (from 1956) of the Swedish Academy of Sciences.

Tiselius, a Nobel Prize winner (1948), was a professor of biochemistry and the director of the Institute of Biochemistry at Uppsala (1938–68). His work dealt mainly with techniques for electrophoretic and chromatographic research on macromolecular compounds. Tiselius also demonstrated the complex nature of serum proteins.
