General description

Chicken IgY is made of two heavy (H) and two light (L) chains. Its molecular weight is about ~180 kDa.
Chicken IgY is the major antibody found in chicken serum. Chickens generate a comparatively enhanced antibody response to mammalian antigenic proteins. These immunoglobulins do not bind to Fc receptors present in mammals and bacteria, and also do not interact with rheumatoid factors. Thus chicken antibodies are useful analytical tools for various research applications .

Specificity

Birds, reptiles and amphibians express IgY antibodies that are functionally equivalent to IgG. Anti-Chicken IgY (IgG) (whole molecule)-FITC antibody is specific for IgY of chicken. Rabbit Anti- Chicken IgY (IgG) is conjugated to fluorescein isothiocyanate (FITC). Free FITC is removed by gel filtration.

Chicken IgY (IgG)
Purified chicken IgY (IgG)

Application

Anti-Chicken IgY (IgG) (whole molecule) FITC antibody has been used:
  • in indirect immunofluorescence
  • in western blotting
  • in immunocytochemistry

Biochem/physiol Actions

IgY plays a major role in defense mechanism against systemic infections. It also possesses the ability to initiate anaphylactic reactions.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
