Arne Tiselius

Died 29 Oct 1971 at age 69 (born 10 Aug 1902). Arne Wilhelm Kaurin Tiselius was a Swedish biochemist who won the Nobel Prize for Chemistry in 1948 for his work on electrophoresis and other new methods of separating and detecting colloids and serum proteins. In 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. 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 chromatography (from 1940) and partition and gel filtration (from the late 1950s).
