Fig 10.

Mean reactivities (MFI) of 38 XMRV antigens (synthetic peptides and recombinant proteins). The upper section (ME) shows the reactivities of 85 sera from ME/CFS and fibromyalgia patients, diluted 1/100. The lower section (BD) shows the reactivities of 254 blood donor sera diluted 1/100. The asterisk indicates that two outlying values were removed. The panel of antigens was somewhat different from the ones shown in Fig. 9; this was due to the successive production of new recombinant proteins and limited availability of xMAP beads. The result with the one degenerate peptide in this experiment is boxed.
