Custom Chicken Antibody Production

The chicken is an ideal choice as a non-mammalian host species when using mammalian or human protein antigens. Since chickens are not mammals they generally produce high avidity antibodies to mammalian antigens, especially those that are highly conserved. This is due to the fact that the protein structure of mammalian proteins is similar between different species.

Some of the other advantages of IgY antibodies in the chicken are that:

• The process of collecting the antibodies is much less invasive in comparison to other host species as the antibodies are found within the yolk of the egg.
• Approximately 2-3g of antibody can be collected from one chicken in one month
• IgY does not bind to protein A/G
• IgY antibodies do not recognize mammalian Fc receptors
• Generally a specific antibody response can be seen much quicker than in mammalian host species
• Eggs can be stored at 4ºC for at least 6 months without a reduction in the quality
