Arne Tiselius

Swedish biochemist and Nobel laureate

Arne Wilhelm Kaurin Tiselius (10 August 1902 – 29 October 1971) was a Swedish biochemist who was awarded the Nobel Prize in Chemistry in 1948 for his research on electrophoresis and adsorption analysis, particularly for his discoveries concerning the complex nature of the serum proteins.

Early life and education

Arne Tiselius was born in Stockholm, Sweden, and moved to Gothenburg with his family at a young age. He showed an early interest in science and pursued his studies at the University of Uppsala, where he was influenced by the work of Theodor Svedberg, a prominent chemist and Nobel laureate. Tiselius completed his Ph.D. in 1930, focusing on the electrophoretic analysis of proteins.

Career and research

Tiselius's career was marked by his pioneering work in the field of biochemistry, particularly in the development of methods for the separation and analysis of complex mixtures of proteins. His most notable contribution was the development of the Tiselius apparatus, an advanced form of electrophoresis that allowed for the separation of proteins based on their charge and size.

Electrophoresis

Electrophoresis is a technique used to separate charged molecules in a fluid using an electric field. Tiselius's innovations in this area provided a powerful tool for the analysis of biological molecules, which was crucial for the advancement of biochemistry and molecular biology. His work laid the foundation for many modern techniques used in laboratories around the world today.

Adsorption analysis

In addition to his work on electrophoresis, Tiselius also made significant contributions to the field of adsorption analysis. This involves studying how molecules adhere to surfaces, which is important for understanding various biochemical processes. His research in this area helped to elucidate the behavior of proteins and other macromolecules in biological systems.

Nobel Prize

In 1948, Arne Tiselius was awarded the Nobel Prize in Chemistry for his research on electrophoresis and adsorption analysis. The Nobel Committee recognized his work as a major advancement in the understanding of the complex nature of serum proteins, which are essential components of blood plasma.

Later life and legacy

Tiselius continued to be active in the scientific community throughout his life. He served as a professor at the University of Uppsala and was involved in various scientific organizations. His contributions to biochemistry have had a lasting impact, influencing generations of scientists and researchers.
