Fiske and subbarow method
WebWith Yellapragada Subbarow (1895-1948), he is credited with developing the colorimetric method for the estimation of phosphorus in solutions in 1925, and with discovering, isolating, and describing two chemical compounds involved in muscle metabolism: phosphocreatine in 1927 and adenosine-triphosphate in 1929. WebFiske and SubbaRow were able to demonstrate that much of the phosphate in muscle filtrates was not inorganic phosphate, as had been believed, but a compound that was equimolar creatine and phosphate. They also were able to show that phosphocreatine …

WebA simple method of inorganic phosphate determination for colored and/or turbid biological samples is described. The procedure is mild, and so is suitable for routine phosphohydrolase assays. ... following its extraction in organic solvents or by a modified Fiske and Subbarow method.

(for acid-soluble phosphorus in blood) destroy organic matter by heating with sulfuric and nitric acids, precipitate the phosphates as magnesium ammonium phosphate, and reduce the precipitate with para-amino-naphthol-sulfonic acid. Compare the blue color with a standard phosphate solution. 2. (for inorganic phosphates) …

WebThe work at the University of Pittsburgh was aided by a grant from the National Foundation for Infantile Paralysis, Inc.; that at Harvard University by research grant E-1023-C from the National Institute of Allergy and Infectious Diseases, National Institutes of Health, Public Health Service, and the Lederle Laboratories Division of American Cyanamid Company. WebThe popular Fiske-Subbarow method (1) requires too much material for our purpose. The use of stannous chloride as a reducing agent for determination of phosphate in biological material was first suggested by Denig&s (2). It was later used by Kuttner and Cohen (3) and modified by Kuttner and Lichtenstein (4). These writers reported that the blue ...
WebIn the Fiske-Subbarow colorimetric method for the determination of phosphate, the color yield is directly proportional to the amount of inorganic phosphate only when the aliquot taken for analysis contains between 0.1 and 1.0 µmole of phosphate. The efficiency of the enzymatic formation of glucose-1-phosphate will vary somewhat
WebWith 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.
