Goat anti-rabbit IgG, FSD™ 647 is a fluorescence conjugated secondary antibody that displays excellent optical imaging with low cross reactivity. Anti-rabbit secondary antibodies display specificity for rabbit IgG and are useful for the detection of specific target. Since multiple secondary antibodies can bind to a single primary antibody, Goat anti-rabbit IgG, FSD™ 647 might provide the great sensitivity in signal amplification, visualize low abundant targets and reduce experimental time. FSD Fluor™ is a new generation of dye series with superb fluorescence intensity and high quantum yield comparing to traditional dyes. FSD™ 647 might be excited using 593 or 633 nm laser line and displays excellent optical property. We offer Goat anti-rabbit IgG, FSD™ 647 as a suitable fluorescent molecular probe for many biological experiments such as fluorescence microscopy, flow cytometry, microplate assays, protein and nucleic acid blots, in situ hybridization, etc.
