What is the concentration of antibody in egg yolk?
The concentration of antibody in the egg yolk is somewhat higher than that found in serum. Whereas human serum typically contains IgG at 10-12 mg/ml, egg yolk contains IgY at 15-25 mg/ml (Akita and Nakai, 1993). Presumably, this high concentration is important for conferring passive immunity to newly hatched chicks.
