Immunoreactivity of IgY throughout the (A) production and (B) storage process. Tablets were stored in a dark room at room temperature from the date of manufacture to the date of testing. Sample concentrations were normalized before plotting. Immunoreactivity of IgY was tested against Wuhan variant S1 protein at different antigen: IgY dilution ratios.
