Abstract |
Egg yolk immunoglobulin (IgY) is much widely used in medical fields, but its use in serology of plant viruses is much limited. We produced an IgY against pepper mild mottle virus (PMMoV) and applied it to several serological tests. Polyclonal antibodies were obtained from the egg yolk of chicken immunized with a total of 2mg of purified PMMoV over 2 months. The titers of antibodies were measured with the ring-test over six months after the first injection. The highest titers of IgY was 1/2,560 at 2 months after the first injection. Approximately 60-80 mg of IgY were obtained from one egg yolk. Using the IgY, 1 ng/ml of purified PMMoV was detected with the indirect ELISA. Gelrite gel double diffusion test, ELISA and tissue immuno-binding assay employing IgY gave similar sensitivity and specificity to those of IgG developed in rabbit. Therefore, the IgY which can be obtained in large quantities from a chicken, might be useful for the antibody production and the serology of plant viruses. |
