General description
Dabsyl chloride (4-dimethylaminoazobenzene-4′-sulfonyl chloride) is a chromophoric labeling reagent used in HPLC for derivatizing amino acids. It reacts freely with all amino acids in order to form dabsyl amino acids, which are photostable and can be seen on a thin-layer chromatographic plate.
Application
For the qualitative and quantitative identification of amino acids and for the determination of N-terminal amino acids. Used in the determination of primary and secondary amines by HPLC.

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
