Goat F(ab')2 Anti-Mouse IgG H&L Antibody (CF®543) (A343733)

HeLa cells were stained with mouse anti-tubulin followed by CF®543–conjugated goat anti-mouse secondary antibodies to label microtubules in red, and with CF®488A Mix-n-Stain™–labeled mouse anti-transferrin receptor to visualize endosomes in green.

Normalized emission spectra of the CF® dye family spanning the visible to near-infrared range are shown, illustrating the spectral diversity and overlap between dyes. Curves represent relative fluorescence intensity as a function of emission wavelength (nm), with peak positions corresponding to each dye’s characteristic emission maximum. This reference highlights the broad coverage of CF® dyes for multicolor fluorescence applications and aids in selecting compatible dye combinations for imaging, flow cytometry, and other fluorescence-based assays.

This chart summarizes commonly used CF® dyes grouped by their suitability for specific imaging modalities, including alternative spectra applications, four-color confocal imaging, near-infrared western blotting, photoacoustic imaging, STED, SIM, STORM, TIRF, and two-photon microscopy. Each dye is shown with its characteristic excitation and emission wavelengths (nm), providing a practical reference for selecting spectrally compatible dyes and optimizing multicolor experimental design across a range of fluorescence techniques.
