The isolation of IgY from egg yolk is a crucial process in immunology, particularly for the development of immunodiagnostic tools and therapeutic applications. IgY, or immunoglobulin Y, is the primary antibody in birds, reptiles, and amphibians, and it is present in high concentrations in egg yolk. The process involves several key steps, including the collection of egg yolks, followed by the extraction and purification of IgY using techniques such as precipitation, chromatography, or dialysis.
