A complex phosphotungstomolybdic acid reagent which oxidizes phenolic compounds under alkaline conditions and is itself reduced from a yellow to a blue colour. Examples of its use are the estimation of total protein by its reaction with tyrosine residues and the measurement of phenol liberated by alkaline phophatase in the King-Armstrong method. [Pg.139]
