Abstract

The current trends for pursuing research programmes warrant abundant, non-invasive experimentation techniques avoiding the use of laboratory animals have led to a search for alternate sources of commercial antibodies for various immunodiagnostic and prophylactic assays. The present experiment exploited the diagnostic property of egg immunoglobulins (IgY) against infectious bursal disease (IBD) as a novel, alternative approach. The anti-IBD -IgY was harvested by the water dilution method, purified by salt precipitation, characterized by SDS - PAGE and assessed for its purity by immunoelectrophoresis. An average 200 - 250 mg. of immunoglobulins were harvested from an egg with 57-60% recovery of specific immunoglobulins. The anti - IBD-IgY thus harvested was found to possess immunodiagnostic potency as assessed by agar gel precipitation test and counter immunoelectrophoresis for replacing the use of conventional antibody.
