Fiske subbarow method

WebIn 1925, Fiske and Subbarow1 described a method for the determination of phosphorus in protein-free blood filtrates using ammonium molybdate. Aminoaphtholsulfonic acid was employed as a reducing agent. Many reducing agents have since been introduced, among them ferrous sulfate (first introduced by Summer2). This methodology offered the ... WebBartlett (6) improved the sensitivity of the widely used method of Fiske and SubbaRow (4). Heating at 100°C resulted in a 7.2-fold in- crease in sensitivity with a molar absorbance at 830 nm of 2.6 X lo4 M-%rn-l in comparison to 3.6 x 10” M-*cm-* at 660 nm obtained with the other procedures.

Webbiochemist. Born: 1/12/1895. Birthplace: Bhimavaram, India. The young Yellapragada SubbaRow flunked out of two high schools in India until the death of his father caused him to buckle down to his studies. He studied math, physics, and chemistry before being accepted to Madras Medical College, where he became interested in medical research. After earning a diploma from the Harvard Medical School he joined Harvard as a junior faculty member. With Cyrus Fiske, he developed a method for the estimation of phosphorus in body fluids and tissues called the Fiske-SubbaRao Method. He also discovered the role of phosphocreatine and adenosine triphosphate (ATP) in muscular activity, which earned him an entry into biochemistry textbooks in the 1930s. He obtained his Ph.D. degree the same year. He joined Led…
