Scientific context

Total pre-immune IgY is purified from egg yolks of hens not immunized with any antigens.


Complexes, systems, regulators, immune RNAs and non immune controls that can react with a specific antigen epitope.


total IgY have been isolated by a PEG precipiation method from a pool of eggs from not immunized hens. IgY has been determined to have a purity over 80 % by SDS PAGE gel electrophoresis.

Storage condition

store at 4°C; make aliquots to avoid working with a stock. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from liquid material adhering to the cap or sides of the tubes.


Chickens like all bird species have IgY antibodies that are very stable and found in the yolk. Gallus Gallus domestica is the Latin name of the Chicken.Chicken yolk polyclonal Immunoglobulin Y (abbreviated as IgY) is a type of immunoglobulin which is the major antibody in bird, reptile, and lungfish blood. It is also found in high concentrations in chicken egg yolk. As with the other immunoglobulins, IgY is a class of proteins which are formed by the immune system in reaction to certain foreign substances, and specifically recognize them.
