FluoTag®-X2 anti-Chicken IgY

Cat No: N0702 Category:


FluoTag®-X2 anti-Chicken is a species-specific FluoTag® directed against immunoglobulins from Chicken.

The immune repertoire of chickens is much simpler compared to the one of mammals, producing only one isotype of immunoglobulins (IgY) with no subclasses. The use of polyclonal antibodies raised in chicken has steadily grown over the last years, mainly due to the need to add a new “species” when performing multitarget immunofluorescence.

Our sdAbs anti-chicken IgY binds strongly and specifically to all chicken IgYs.

FluoTags® can be equipped with a single fluorophore for more quantitative readouts (FluoTag®-Q), with two fluorophores per single-domain antibody (FluoTag®-X2), and we also developed a blend of two sdAbs bindings simultaneously the target proteins and each bearing two fluorophores (FluoTag®-X4). For more detailed information on the FluoTags, please check our Technology Section.

Capacity: N/A
Antigen: -
Targets: Chicken IgY
Specificity: Chicken IgY
Formulation: The single sdAb clone was lyophilized from PBS pH 7.4 containing 2% BSA (US-Origin). Reconstitute with 500 µL of 50 % glycerol in deionized water. We recommend including 0.1 % sodium azide as a preservative if applicable. When reconstituted with 500 µl, the concentration of single-domain antibody is 5.0 µM.

Shipping: Ambient temperature
Storing: Vials containing lyophilized protein can be stored at 4 °C for 6 months. We recommend reconstituting the protein with 50 % sterile glycerol including 0.1 % sodium azide as preservative if applicable. Minimize the number of freeze-thaw cycles by aliquoting the reconstituted protein. Long term storage at -80 °C for up to 6 months. Working aliquots can be stored at -20 °C for up to 4 weeks. We do not recommend storing the reconstituted protein at 4 °C.
