formulation of 1-amino-2-naphthol-4-sulfonic acid, sodium sulfite and bisulfite according to C.H. Fiske and Y. Subbarow, J.Biol.Chem. 66, 375 (1925)
Application
The Fiske-Subbarow assay is a colorimetric assay designed to measure levels of inorganic phosphate in biological samples. Fiske-Subbarow reducer reagent is used as the reducer component of the Fiske-Subbarow assay.
We describe the development of a rapid colorimetric assay for soluble guanylate cyclase (sGC) activity adapted for a 96-well microplate. The assay greatly decreases the analysis time and cost over traditional methodologies based on radio- and immunoassays and high-performance liquid
Methods for detecting and measuring the success of nucleic acid sequence amplifications can be developed by detecting the by-products of amplification procedures. One method includes the detection of inorganic phosphate (Pi) during or on completion of the PCR. The method
A new colorimetric procedure is described for inorganic phosphate determination using the color reaction between inorganic phosphate and acidified ammonium molybdate in the presence of Triton X-100. The method is simple and specific, and produces results comparable with those of
The colorimetric determination of phosphorus
