IgG isotypes profile against
KMP-11 recombinant protein. IgG1 (5A), IgG2 (5B), IgG3 (5C) and IgG4 (5D) isotype levels for patients in acute (AC), indeterminate (IND) and cardiac chronic phase (CCC) and healthy individuals (HD). Values are given as optical densities at 492 nm. The dotted line represents the cut-off values based on the mean of healthy individual values plus 3 standard deviations. Horizontal lines on each group represent the mean and standard deviation values, the mean being the larger one.
