Figure 4

Intensity values of FAM36A shown for all COPD and control sera. A: FAM36A intensity values shown for each serum. Blue circles indicate sera of COPD patients and red circles indicate control sera. B: Distribution of seroreactivity signals according to their intensities. Seroreactivity signals that stem from controls are indicated in blue, and seroreactivity signals that stem from COPD sera are indicated in green. The overlaps are indicated in yellow. For this clone, signals with low intensities are mostly found with COPD sera and signals with higher intensities are mostly found with control sera.
