ABSTRACT:
Novel fluorescent dyes based on the dipyrrometheneboron difluoride structure are provided. The new reagents contain functional groups capable of forming a stable fluorescent product with functional groups typically found in biomolecules or polymers including amines, phenols, thiols, acids, aldehydes and ketones. Reactive groups in the dipyrrometheneboron difluoride dyes include activated esters, isocyanates, amines, hydrazines, sulfonyl halides, acids, aldehydes, alcohols and haloacetamides. The products are detected by their absorbance or fluorescence properties. The spectral properties of the fluorescent dyes are sufficiently similar in wavelengths and intensity to fluorescein as to permit use of the same euqipment. The dyes, however, have narrower spectral bandwidths than fluorescein, do not show appreciable sensitivity to pH, have higher solubility in non-polar solvents and have improved photostability.
