5(6)-Carboxynaphthofluorescein (CBNF; CAS 163831-68-3) reagent, recommended as a live cell dye to use with the Agilent Cell Kit (Cat# 5067-1519). Product discontinued (Thermo Cat# C13196), but recommended in your document "Monitoring transfection efficiency by green fluorescent protein (GFP) detection with the Agilent 2100 bioanalyzer, Agilent Technologies Application Note, (2001), publication #5988-4320EN."
Molecular Probes #C13196 (descontinuado) - Carboxynaphthofluorescein diacetate (CNFDA) (C13196, 
), which is cleaved by intracellular esterases to yield red-fluorescent carboxynaphthofluorescein (excitation/emission maxima ~598/668 nm), is the only long-wavelength tracer of this type that can be passively loaded into live cells.
Like chloromethyl SNARF-1 acetate, carboxynaphthofluorescein diacetate is usually used in combination with a green-fluorescent tracer for detecting cell–cell interactions.[1].

Molecular Probes #C653 5-(and-6)-Carboxynaphthofluorescein, Succinimidyl Ester, mixed isomers
Naphthofluorescein has emission maxima of approximately 670 nm in aqueous solution at pH 10. The fluorescence from this dye is pH dependent (pKa ~7.6) requiring a relatively alkaline pH for maximal fluorescence. T The amine reactive 5-(and-6)-carboxynaphthofluorescein succinimidyl ester can be used to couple this fluorophore to biomolecules of interest.
