These three dyes, BP Fluor 647, Cyanine 650, and Cy5, are bright green-fluorescent dye optimal for use with the 633, 650 nm argon laser. The three dyes have the same fluorophore backbone structure which contributes to the almost identical absorption and emission spectrum. They are only different from the number of soluble groups SO3Na, i.e. Cy5 has two SO3Na groups, and Cyanine 650 has three while BP Fluor 647 has four. <br /> All these dyes are water soluble and pH-insensitive from pH 4 to pH 10. The sulfonate groups make it high water soluble and less aggregation in the aqueous solution. These dyes are used for protein and antibody labeling, or nucleic acid applications with high labeling density for numerous bio applications.

800CW (IRDye 800CW acid equivalent) is a near-infrared fluorescent dyes. The unique structure has 4 sulfonates which make it as a high water soluble and less aggregation in aqueous solution. 800CW is used for protein and antibody labeling, or nucleic acid applications with high labeling density.<br /> 800CW dye-conjugated agents and probes are currently propelling more than a dozen Phase I or Phase II clinical trials, more than any other near-infrared fluorescent dye based on its enhanced sensitivity due to low background autofluorescence in the near-infrared region and, therefore, higher signal-to-noise ratios.

The fluorescein labeling kits are high-performance derivatives of fluorescein dye, activated for easy and reliable labeling of antibodies, proteins and other molecules for use as fluorescent probes.<br /> Fluorescein dyes are used in wide-ranging applications including fluorescence microscopy, flow cytometry and immunofluorescence-based assays such as Western Blotting and ELISA. Fluorescein NHS are reactive toward primary amine groups on proteins, peptides and other biomolecules, while fluorescein-maleimide reacts with free sulfhydryls on cysteine residues.<br /> <br /> Most activated fluorescein derivatives are mixtures of isomers with reactive groups attached at the 5- and 6-positions of the bottom ring. There is a big difference in flow cytometry although it is a small difference in the properties of these isomers in terms of excitation and emission spectra. The small difference will make your assay complicated because the ratio of two isomers varies lot by lot.<br /> <br /> BroadPh
