  • Patent number: 7863048
    Abstract: Protein dyes whose molecular structure is that of a coumarin moiety coupled to a quaternary ammonium heterocycle through a vinyl or polyvinyl linkage demonstrate the ability to associate with proteins in a non-covalent, non-specific manner at low pH, where the associated form displays a significantly higher fluorescence emission than the unassociated form. This makes the dyes useful as selective labels for proteins at the low pH and eliminates the need for the removal of extraneous components from the medium in which the proteins reside prior to detection.
