A fluorescent label compound of formula n nwhere Z is a reactive group that can be used for covalent coupling of the fluorescent label compound to other molecule. Either the fluorophore is a dipyrrometheneboron difluoride dye and Y is a water-solubilizing moiety, or Y is —CH 2 CH 2 SO 3 − X + where X + is a cation. The use of the compounds in bianalytical assays and cytological or histological staining methods, and a method for increasing the hydrophilicity of fluorescent compounds, are also disclosed. |
