A: PEG precipitated antigen, B: cell debris derived antigen and A + B: a combination of A and B tested with positive and negative sera diluted 1:100 and conjugate diluted 1:20 000. Bars shows optical density (OD) for positive serum, lines shows ratio between positive and negative sera (P/N value).Back to article page
