Titration curve of IgY production. A group of two chickens was immunized with 0.1 mg of diphtheria toxoid on days of 0, 18, 43, and 62. The level of IgY was determined by indirect ELISA using diphtheria toxoid. Each experiment was performed in two replicates, and the mean ± SD of samples was represented. All Data are normalized against the mean value of the control group injected by PBS and adjuvant
