20 candidate autoantigens identified in Phase I.
A, Heat map of the signals obtained from the 20 candidate autoantigens in the HuProt array experiments. B, Two candidate autoantigens, namely CTDP1 and PRAMEF12, were found specifically identified by serums from the BD patients, but not from TA, SS and normal (Nor) groups on HuProt microarrays. C, Boxplot analysis of three other candidate autoantigens.
