  • ICC/IF image of ab89984 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then incubated in 1%BSA / 10% normal donkey serum / 0.3M glycine in 0.1% PBS-Tween for 1h to block non-specific protein-protein interactions. The cells were then incubated with the primary antibody (ab89984, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab150169 Alexa Fluor® 488 goat anti-chicken IgY (H+L) used at 1µg/ml for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    The negative control (inset) is a secondary-only assay to demonstrate low non-specific binding of the secondary antibody.

I am happy to confirm that ab150169 (Goat Anti-Chicken IgY H&L (Alexa Fluor® 488)) is a suitable secondary antibody for ab13970 (Anti-GFP antibody (ab13970)).

I would like to note that chicken IgY and chicken IgG are the same kind of immunoglobulin.

The nomenclature sometimes is not very clear as IgY is often mislabeled as Immunoglobulin G (IgG) in older literature, and sometimes in commercial product catalogs, due to its functional similarity to mammalian IgG

Chicken IgY is the major circulating antibody found in chickens and is the avian counterpart to mammalian IgG’s. IgYs are equivalent to IgGs in most applications, including Western Blotting, ELISAs, immunohistochemistry, immunocytochemistry.

IgYs have the same structure as a mammalian IgG, with 2 heavy (“nu” chains, ˜67-70 kDa) and 2 light chains (22-30 kDa)

Unlike the gamma-chains of IgG, however, the heavy chains of IgYs lack Fc domains, which means that IgYs do not fix complement nor bind protein A or protein G.
Chickens also produce an alternatively-spliced form of the heavy chain in which the Cnu3 and Cnu4 domains are deleted. In some individual animals, this F(ab)2-like heavy chain can be seen running at 40 kDa in SDS-(10%) polyacrylamide gels.
