anti-Mouse IgG kappa light chain sdAb - FluoTag-X2 - N1202-Li800-S

Secondary single domain antibody specific for mouse IgG with a kappa light chain


This product was developed by   


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.

Camelid single domain antibody

Unlabeled variants and several modifications of sdAbs like biotin, fluorophore or DBCO conjugation are available.


FluoTag®-X2 anti-Mouse is a species-specific FluoTag® directed against the κ light chain of mouse.
In FluoTag®-X2, two fluorophore molecules are coupled site-specifically to one individual FluoTag® molecule. Therefore, the reagent targets four fluorophores to your primary mouse antibody.
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.
