Fiske subbarow method protocol
WebThe conventional method of Fiske and Subba Row for the estimation of inorganic phosphate (Pi) is although rapid, but suffers from the disadvantage that the color is unstable and hence the optical density (OD) measurements have to be carried out within a short … WebThe first method uses a commercial kit obtained from Sigma Diagnostics, based on the original Fiske-Subbarow chemistry, and offers the convenience of ready-made reagents. The second method 2 is approximately 10 times more sensitive, and thus is useful for samples containing 0.1 to 5.0 µg Pi/mL . Whichever method is used, the SPECTRAmax …
