anti-Chicken IgY sdAb - N0705-DBCO

A monovalent single domain secondary antibody specific for chicken IgY


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
Cat. No.: N0705-DBCO
Amount: 250 µg
Price: $770.00
Cat. No. N0705-DBCO 250 µg purified antibody, lyophilized from PBS, fluorescence-labeled with DBCO.

Dibenzocyclooctyne (DBCO, ADIBO) is one of the most reactive cycloalkynes for strain promoted alkyne azide cycloaddition (spAAC), a copper-free click chemistry reaction.

Albumin was added for stabilization. For reconstitution add 250 µl H2O to get a 1mg/ml solution in PBS. Either add 1:1 (v/v) glycerol, then aliquot and store at -20°C until use, or store aliquots at -80°C without additives.
Reconstitute immediately upon receipt! Avoid bright light when working with the antibody to minimize photo bleeching of the fluorescent dye.

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


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.
