anti-Chicken IgY sdAb - FluoTag-X2 - N0702-AF-S

Secondary single domain antibody specific for chicken IgY


This product was developed by   


FluoTags are camelid single domain antibodies consisting only of one antigen binding site of a Alpaka heavy chain antibody. With only ~15 kDa, these Tags are about 10-times smaller than conventional IgG antibody molecules.

Documents data sheet

ICC: This antibody is intended to be used for uptake experiments in cell cultures. Primary antibodies against extracellular epitopes can be pre-labeled with this FluoTag. The pH sensitive dye regaines its fluorescence after the reacidification of the intracellular compartment.

IgY is the major immunoglobulin found in chicken eggs. FluoTag®-X2 anti-chicken is a species-specific FluoTag®-X2 directed against immunoglobulin IgY from chicken.
In FluoTag®-X2, two fluorophore molecules are coupled site-specifically to one individual FluoTag® molecule. Therefore, the reagent targets four fluorophores to your primary chicken 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.
