| Abstract: | Abstract] Objective To observe the activity of anti - rabies virus IgY 24h after being digested with pepsin. Methods The anti - rabies virus IgY with a high liter was crudely extracted, digested with pepsin, and purified, and the activity of it was detected by ELBA and neutralizing test in mice. Results A single fragment with a relative molecular weight of 4.6798 was obtained. The fragment could neutralize rabies virus. Conclusion The neutralizing activity of the IgY was still maintained after being digested with pepsin for 24h. The study laid a foundation of developing oral vaccine. |
