Excellent condition.(1917-1985) Prof Rodney Robert Porter was a British biochemist and Nobel laureate.Porter was elected a Fellow of the Royal Society (FRS) in 1964. He won the Gairdner Foundation International Award in 1966. In 1972, Porter shared the Nobel Prize in Physiology or Medicine with Gerald M. Edelman for determining the chemical structure of an antibody. Using the enzyme papain, he broke the blood's immunoglobin into fragments, making them easier to study. He also looked into how the blood's immunoglobins react with cellular surfaces. He subsequently worked with colleagues Kenneth BM Reid, Robert Sim, and Duncan Campbell on developing an understanding of the Complement Proteins associated with defense against infection.This lot came from the Jim Wiggins collection we purchased in July 2022. Jim Wiggins accumulated the most unique and valuable autograph collection over a period of 70-plus years. He obtained his collection either in person or by writing to persons of fame and notoriety. Comes with a full Letter of Authenticity from Todd Mueller Authentics.
