Abstract:
Reagents comprising MS active, fluorescent molecules with an activated functionality for reaction with amines useful in tagging biomolecules such as N-glycans and uses thereof are taught and described. In particular, compounds for use as a reagent for rapid fluorescence tagging of biomolecules and enhanced MS signaling are provided. The compounds may have optical centers and therefore may occur in different enantiomeric and diastereomeric configurations. These MS active, fluorescent compounds may have three functional components: (a) a tertiary amino group or other MS active atom; (b) a highly fluorescent moiety, and (c) a reactive group that rapidly reacts with amines. The reactive group provides rapid tagging of desired bio-molecules. The fluorescent moiety provides the fluorescent signal. The tertiary amino group provides the MS signal.
