Camelid single domain antibodies (sdAbs) consist only of one antigen binding site of an Alpaca heavy chain antibody. With only ~15 kDa, these Tags are about 10-times smaller than conventional IgG antibody molecules.
|Cat. No. N2405-250ug||250 µg purified antibody, lyophilized from PBS. For reconstitution add 250 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use.|

This single domain antibody carries a C-terminal cystein available for conjugation.
Unlabeled variants and several modifications of sdAbs like biotin, fluorophore or DBCO conjugation are available.
FluoTag®-X anti-Rabbit is a species-specific FluoTag® directed against the IgG from Rabbit. In FluoTag-X2, two fluorophore molecules are site-specifically coupled to one individual FluoTag molecule. The reagent therefore targets four fluorophores to your primary Rabbit antibody. FluoTag-X4 is a blend of two nanobodies carrying two fluorophores each. 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 FluoTags are recombinantly expressed, there is no batch-to-batch variation.
