摘要

Process for isolating selectively IgY antibody from egg yolk of a bird anseriforme and IgY antibodies obtained from the same.Which refers mainly to a process for isolation and purification of yolk antibody from egg yolk of a bird anseriforme, through a chromatographic procedure of adsorption using an absorbent insoluble in water not loaded to perform the separation desejad The yolk antibody.And a procedure of precipitation of proteins by increase of salt concentration that precipitates, differential form, the IgY antibodies. The present invention also refers to the yolk antibodies produced here and to various uses of these antibodies in egg yolk.
