Fig. 5From: Development of an enzyme-linked immunosorbent assay based on viral antigen capture by anti-spike glycoprotein monoclonal antibody for detecting immunoglobulin A antibodies against porcine epidemic diarrhea virus in milkDetermination of the sensitivity of the developed ELISA. Four PEDV IgA antibody positive and one negative milk samples were two-fold serially diluted as 1:40, 1:80, 1:160, 1:320, 1:640, 1:1280, 1:2560. The sensitivity of the developed ELISA was determined using the diluted milk samples. The error bars indicate SD valuesBack to article page
