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. Far red fluorescent CF™640R has excitation/emission maxima at 642/662 nm, similar to Cy®5. CF™640R produces highly fluorescent antibody conjugates, and has the best photostability among spectrally similar dyes.
