Rabbit anti-goat IgG, Flamma® 749 is a fluorescence conjugated secondary antibody that displays excellent optical imaging with low cross reactivity. Anti-goat secondary antibodies display specificity for goat IgG and are useful for the detection of specific target. Since multiple secondary antibodies can bind to a single primary antibody, Rabbit anti-goat IgG, Flamma® 749 might provide the great sensitivity in signal amplification, visualize low abundant targets and reduce experimental time. Flamma® Fluor dyes feature strong absorption, high fluorescence quantum yield, and high photostability. Flamma® 749 might be excited using 750 nm laser line or dye-pumped laser excitation and the emission occurs at biological tissue permeable NIR region. We offer Rabbit anti-goat IgG, Flamma® 749 as an optimal molecular probe for many biological experiments such as fluorescence microscopy, flow cytometry, microplate assays, protein and nucleic acid blots, in situ hybridization, etc.
