Invitrogen™ ATTO-TAG™ FQ Derivatization Reagent (FQ; 3-(2-Furoyl)quinoline-2-Carboxaldehyde)

Recently, researchers described a simple method in which the ATTO-TAG FQ reagent was used to derivatize very dilute solutions (10^-8 M) of peptides. Available as standalone product or as component of an amine-derivatization kit (A-2334). Particularly well-suited to derivatization of peptides, amino acids, aminated sugars and other amine-containing molecules for detection by capillary electrophoresis with laser-induced fluorescence, as its nonfluorescent in unreacted state and reacts specifically with amines to form highly fluorescent conjugates.
