SubbaRow assay procedure. The extent of interference observed is dependent on the pH of the final assay system; small changes in pH at low pH values lead to large variations in the amount of ATP interference. Addition of excess ammonium molybdate and neutralisation of any previous acid additions (su

โฆ Synopsis
The influences of ATP and trichloroacetic acid on the color development of molybdenum blue in the Fiske and Subbarow method for the determination of inorganic phosphate were investigated. From these results optimum concentrations of ATP and trichloroacetic acid were recommended. Satisfactory results were obtained in the determination of the ATPase activity of sarcoplasmic reticulum membranes isolated from rabbit skeletal muscle. 40

In kinetic studies on erythrocyte membrane ATPase, the activity is assayed by following the release of orthophosphate from ATP by the Fiske-SubbaRow method. The deproteinization of the samples, which is essential before assay by this method, is an obstacle to the quick and efficient assay of large n
