Representative examples of cell-ELISA. The panels show cell-ELISAs performed on healthy controls. Different individual profiles can be observed using the assay performed in 384-well plates. Tested antigens included CMV (CMV lysate, pp65 peptide mix, and immunodominant CD4 and CD8 peptides from pp65), recall antigens (TT and PPD), adenovirus hexon 5 and EBV LMP2 peptide mixes, fungal antigens (Candida albicans [Ca], Aspergillus niger [Asp niger], and Aspergillus fumigatus [Asp fum]). Adeno, adenovirus.
