WebThe method has been developed for the purpose of obtaining more accurate figures for the phosphorus content of the whole blood and its separate fractions (plasma, serum and red cells) than those... 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.
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 ... WebIn the Fiske and Subbarow method, we noticed that the time factor plays a role in the interference of the phytic acid; especially the readings taken during the second hour of incubation are influenced by the presence of phytic acid. The method of Cooper and Gowing is labor-intensive and is prone to give error values at higher concentrations.
WebJan 1, 1978 · The method is modified extensively from that of Fiske and SubbaRow [ (1925) J. Biol. Chem.66, 375] by decreasing 10-fold the level of reducing agent, ANSA, increasing the concentration of ammonium molybdate to 4 m m, utilizing HCl as the only acid present, and incorporating SDS. WebThe Fiske–Subbarow method basically involves the measurement of phosphomolybdate complex formed by interaction of phosphate and ammonium molybdate in the presence of sulfuric acid. [27]
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
