IgY is a type of immunoglobulin and is the major antibody in bird, reptile, and some species of fish blood. It is also found in high concentrations in chicken egg yolk. Chicken IgY is also somethimes referred to as Chicken IgG, as it is the equivalent molecule in chicken as IgG.
IgY is commonly used in research applications. In immunological studies, using immunoglobulin Y against a mammalian antigen produces significantly less cross-reactivity and background than systems in which the antibody/antigen complex are both from mammalian sources. Additionally the chicken immunoglobulin Y demonstrates effective affinity to highly conserved regions across mammalian species, which helps to minimize errant readings and high background noise in assay results.
Fitzgerald Industries offers highly pure Chicken IgY immunoglobulins for use in Western blotting, immunofluorescence, immunohistochemistry, immunocytochemistry, flow cytometryand ELISA.This popular Chicken IgY is >98% pure and is offered as a lyophilized powder.
This Chicken IgY (Non immune) also referred to as Normal Chicken IgY can be used as a control or blocking reagent in ELISA. We also offer Chicken Ig fraction which has been purified to 95% pure by PEG purification.
