We have developed a new method for the quantification of phosphoserine, phosphothreonine, and phosphotyrosine as dabsyl derivatives in acid-hydrolyzed extracts of 32P-labeled A431 cells. In the first step the phosphamino acids are concentrated using a disposable anion-exchange column. Subsequently, the
