Analysis of the antibody reactivity to the expressed protein antigens. Ag85B, TB10.4 and His-full 2 proteins were adsorbed at different concentrations on ELISA plate (as indicated on abscissa) and tested with active-TB sera at 1:100 dilution. The reactivity is reported as difference of the OD (ΔOD) observed for the sera and in absence of sera as median, 25–75 percentile range (box), and minimum and maximum (line) observed for the 8 tested active-TB patients.
