The Benefits of IgY
Purified antibodies are used in a broad range of applications to detect and quantify proteins. Antibodies are typically produced in mammalian species such as rabbits, but in many cases, chicken antibodies produced from hen eggs (IgY) give improved selectivity, sensitivity and reliability compared to mammalian IgG.
Because IgY production uses eggs and is non-invasive, it is supported by the European Centre for the Validation of Alternative Methods (ECVAM). Furthermore, one hen can produce the same amount of antibody as 10 rabbits in the same time period.
High sensitivity and selectivity
Because IgY originates from hens, it is phylogenetically distant from mammals. Compared to mammalian IgG, avian antibodies produced against mammalian antigens typically have more antigenic epitopes, which results in higher avidity and sensitivity.
High quality and reliability
Our IgY production and animal care facility upholds the highest standards specified in Swedish law and we have been a global supplier of IgY antbodies for over 20 years. Our IgY antibodies are used in a wide range of research and industry applications.
Reduced cross-reactivity
Mammalian IgG typically show a high degree of cross-reactivity with IgG from other mammalian species. In contrast, chicken antibodies do not cross-react with mammalian IgG. Furthermore, they do not bind to or activate platelets, complement, rheumatoid factors, or Protein A/G that may be present in your sample.
