Swedish chemist (1902–1971)

Tiselius was born in Stockholm, Sweden, and educated at the University of Uppsala, where he became the assistant of Theodor Svedberg in 1925. He obtained his PhD in 1930 and his whole career was spent at Uppsala where, in 1938, a special research chair in biochemistry was created for him, which he occupied until 1968.

Tiselius's doctoral thesis was on electrophoresis – a method of separating chemically similar charged colloids. An electrical field is applied to the sample, and particles with different sizes migrate at different rates to the pole of opposite charge, enabling them to be detected and identified. The method was not initially very successful but by 1937 Tiselius had made a number of improvements to the apparatus. Using the technique on blood serum Tiselius confirmed the existence of four different groups of proteins – albumins and alpha, beta, and gamma globulins. Tiselius also conducted work on other methods for the separation of proteins and other complex substances in biochemistry including chromatography (from 1940) and partition and gel filtration (from the late 1950s).

In 1948 he was awarded the Nobel Prize for chemistry for his work on electrophoresis and other new methods of separating and detecting colloids and serum proteins. After the war Tiselius played an important role in the development and organization of science in Sweden, serving (1946–50) as chairman of the Swedish Natural Science Research Council.

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 ultra-centrifuge. 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 felt that its resolution capacity was not sufficiently high. He graduated as a doctor of science at Uppsala in 1930 with a thesis on this work, and he then became assistant professor of chemistry in the University of Uppsala.

As there was no chair of biochemistry in Sweden, Tiselius turned to the inorganic field, and he published research on the diffusion and adsorption phenomena in zeolite crystals. While holding a Rockefeller Fellowship at Princeton University in the United States, he was stimulated to continue his protein studies. On his return to Uppsala in 1935, he redesigned his electrophoretic apparatus and published his new model in 1937. Outstanding among the numerous advances made with his new apparatus was his demonstration that blood serum consists of albumins and of alpha, beta, and gamma globulins. These methods and results were widely used in the United States during World War II, especially in relation to the fractionating of blood serum for transfusion purposes. In 1938 a research chair of biochemistry was created for Tiselius at Uppsala, and he worked at first in Svedberg's Institute of Physical Chemistry. In 1946 biochemistry became an independent department, and in 1950-1952 a new Institute of Biochemistry was built.

In 1940 Tiselius began to work on adsorption methods, and he developed especially the methods of frontal and displacement analyses. In this work he used chromatographic methods, and he developed his technique to provide accurate quantitative results. For his work in these two fields he was awarded the Nobel Prize in 1948.

Tiselius received honorary degrees from 13 universities and many other honors. In 1949 he became a Foreign Member of the National Academy of Sciences in Washington, and in 1957 he was elected a Foreign Member of the Royal Society. He became Vice President of the Nobel Foundation in 1947 and President in 1960. His published work appeared entirely in scientific journals. Tiselius died in Uppsala on Oct. 29, 1971.

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.

Biography

Tiselius was born in Stockholm. Following the death of his father, the family moved to Gothenburg where he went to school, and after graduation at the local "Realgymnasium" in 1921, he studied at the University of Uppsala, specializing in chemistry. He became research assistant in The Svedberg's laboratory in 1925 and obtained his doctor's 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 were continued during a year's visit to H.S. Taylor's laboratory in Princeton with support of a Rockefeller Foundation Fellowship. On his return to Uppsala he resumed his interest in proteins, and the application of physical methods to biochemical problems. This led to a much-improved method of electrophoretic analysis which he refined in subsequent years.

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.

He was married, with two children. He died of a heart attack 29 October 1971 in Uppsala.

The lunar crater Tiselius was named in his honour.
