CF™ dye goat anti-mouse IgG isotype-specific secondary antibody conjugates are labeled with our exceptionally bright, photostable CF™ dyes. The conjugates are prepared from affinity-purified antibodies that react with Fc portion of the heavy chain of mouse IgG1, IgG2a, or IgG2b. To minimize cross reactivity, the antibodies are cross-adsorbed against other mouse IgG subclasses (IgG2a, IgG2b, IgG3), and human, bovine and rabbit serum proteins. Deep red fluorescent CF™594 has excitation/emission maxima at 593/614 nm, and produces significantly brighter antibody conjugates than the spectrally similar dyes Alexa Fluor 594 and Texas Red®. CF™594 also has excellent photostability. Alexa Fluor and Texas Red® are registered trademarks of Molecular Probes Inc.Compatible with the NucleoCounter® NC-3000™.
