Background:

5-(4,6-Dichloro-s-triazin-2-ylamino)fluorescein (DTAF) is an amine-reactive fluorescent probe for labeling proteins.¹It displays excitation/emission maxima of 492/513 nm, respectively. DTAF has been conjugated to IgG for use as fluorescent antibodies and as a pre-column or on-column reagent to label amino acids and amino acid-containing compounds.^1,2,3It has also been used as a derivatizing agent in the analysis of ephedrine and pseudoephedrine from various sources.³
