Tissue protein expression of identified targeted antigens. Proteins are listed by their gene name. (A) The antigen source from which they were identified is highlighted by the green color. (B) The level of protein expression in human tissues for each gene is indicated by the height of the bars as high, medium, or low, based on data from Human Protein Atlas (www.proteinatlas.org). *Antigens selected for confirmation study. N/A, data not available.
