This new FluoTag®-X4 anti-Rabbit (N2404) is a species-specific FluoTag® directed against immunoglobulins from Rabbit. It has a higher affinity to Rabbit IgG molecules compared to our previous FluoTag-X2 anti-Rabbit IgG (Cat. no. N1002). We were able to identify two independent sdAb clones recognizing Rabbit IgG, which allows us to to introduce an X4 version. In our FluoTag-X4 series, two fluorophore molecules are site-specifically coupled to each individual FluoTag molecule. The reagent therefore simulatenously  targets up to eight fluorophores to the protein of interest, which ensures extra-bright signals. Due to the monovalent binding, there are no primary and secondary antibody clusters formed, leading to better epitope accessibility and a more precise localization. Since our FluoTags are recombinantly expressed, there is no batch-to-batch variation.
