Abstract
The present invention provides the method of obtaining IgA and IgM antibodies from chicken egg whites. The method involves separating chicken egg whites into two fractions which contain IgA and IgM antibodies exclusively. This separation method consists of raising the volume of the egg whites using purified water, lowering the pH of said volume, filtering the IgM fraction from said volume, precipitating the IgA fraction from the remaining volume, dialyzing the IgA fraction and drying the IgA and IgM fractions.
Claims11
A method of obtaining avian IgA and IgM antibodies by fractionating the white of the egg of a domestic fowl hen by raising the volume of the egg white containing said antibodies using purified water, lowering the pH of said volume, filtering IgM fraction from said volume, precipitating the IgA fraction from the remaining volume, dialyzing the IgA fraction and drying the IgA and IgM fractions.
