Polson method for IgY isolation with modification. v1

Immunoglobulin Y (IgY) is the mayormolecule present in the avian egg yolk. This protein functions as antibody and fulfils important functions in the protection of the embryo against challenging stimuli [1]. IgY has been isolated from the egg yolk of many birds [1]. These antibodies are important therapeutically, but also they have been used as immunological tool in many immunodiagnostic assays. Much time IgY concentration is calculated from the water soluble fraction (WSF), which means that there is not need of treating the preparation with alcohol to separate the protein pellet.
