This FluoTag®-X4 anti-Rabbit (N2404) is a species-specific FluoTag® directed against immunoglobulins from Rabbit. It has a higher affinity to Rabbit IgG molecules than our previous FluoTag-X2 anti-Rabbit IgG (Cat. no. N1002). We were able to identify two fantastic single-domain antibodies (sdAbs) that can be blended and both bind simultaneously to a Rabbit IgG. This allowed us to introduce the Fluotag®-X4 version. In our FluoTag-X4 series, two fluorophores are site-specifically coupled to each individual FluoTag sdAb clone. Since IgGs are homodimer macromolecules, each Rabbit IgG is decorated by 4 sdAbs when incubated with our FluoTag®-X4 anti-Rabbit, resulting in up to eight fluorophores per single IgG molecule. This ensures extra-bright signals and due to the monovalent nature of FluoTags, there are no probe-induced artifacts by primary and secondary antibody clusters of target molecules, leading to better epitope accessibility and more precise localization for super-resolution microscopy. Since our FluoTags are recombinantly expressed, this blend has no batch-to-batch variation.
Recognizes the native Fc from Rabbit IgG. It does not cross-react with Mouse, Guinea Pig, Chicken, Rat, Donkey, Goat, Pig, Horse, Cow or Human IgGs.
