METHODS FOR PURIFYING IgY ANTIBODIES

摘要

A method for purifying IgY antibodies is provided. The method comprises precipitating IgY antibodies from a sample by contacting the sample with a precipitating agent; and differentially precipitating the IgY antibodies obtained in step (a) using the same or different precipitating agent to separate IgY(Fc) and IgY(DeltaFc) antibodies.
