Studies on the Characteristics of Anti-Zone Antibody I. Identification of Anti-Zona Antibody by Indirect ELISA and Indirect Immunofluorescence Test

항투명대 항체의 특성에 관한 연구 I. 간접효소면역분석법과 간접면역형광분석법에 의한 항투명대 항체의 확인

These experiments were undertaken as a basic study to develop immunocontraceptive vaccine and to understand the role of zona pellucidae in early fertilization process by identifying the monoclonal and polyclonal antibody to porcine zona pellucidae and polyclonal antibody to mouse zona pellucidae by indirect ELISA and indirect immunofluorescence test. The results obtained in these experiments were summarized as follows : 1. The titer of the antibodies to zona was determined by indirect ELISA using solubilized porcine zona coated plates. Both monoclonal and rabbit polyclonal antibodies showed very high titers ; O.D at 1 : 12,800 dilution of antibodies was still significantly higher than that of non-immunized control serum. Rabbit anti-mouse zona pellucidae sera also reacted with porcine zona pellucidae. 2. By indirect immunofluorescence test strong fluorescences were observed on the egg treated with homologous and heterologous rabbit polyclonal antibodies and FITC lablled 2nd antibodies and found to crossreact strongly with the eggs from the pig and mouse. While weaken fluorescences were observed on the eggs treated with monoclonal antibodies.
