Abstrak: Anti rabies serum (ARS) called antibody 1 (Ab1) was used as the antigen to immunize laying chickens. Anti-Ab1 chicken immunoglobulins (IgY), the antiidiotype antibodies against rabies (Ab2) was isolated from chicken blood every week for ten weeks. The highest titer of Ab2 was found at the third week after the last immunization. Immunoglobulin Y was separated by means of ammonium sulfate precipitation, then dialyzed using PBS pH 8.0 for 24 hours at 2 – 8 oC and purified using affinity chromatography column for IgY lead the proteins molecules with 185,000; 95,000 and 49,000 dalton in weigth. Purified IgY was used to immunize New Zealand White rabbit and the antibody response (Ab3) was detected using Agar Gel Precipitation Test (AGPT). The Ab3 showed specific reaction with Ab2 as well as rabies virus. Interestingly, Ab2 and rabies virus express partial identity reaction. This lead the insight, that not all parts of Ab2 are internal image of rabies virus. The efficacy of Ab3 was detected using enzyme linked immunosorbent assay (ELISA) and indicated that the level of Ab3 titer is protective according to WHO standard (more than 0.5 IU/ml).
