Comparison of positive hit distributions. A, Histogram analysis of foreground-to-background ratios of all the protein spots obtained with the 75 samples on the HuProt arrays. The major peaks of all the samples are located between 1.01 and 1.09, indicating that the majority of proteins are not recognized by the serum samples. B, The number of positive proteins identified in each serum profiling reaction varies dramatically from sample to sample. C, The number of positive proteins reacted with serum IgG in BD patients, autoimmune disease control group, and healthy controls were 244.05 ± 206.05, 261.45 ± 249.2, and 261.45 ± 249.2, respectively, without any significant difference.
