Figure 4. Application of pan-human polyomavirus screening to different tissue microarrays.

Figure 4

A Merkel cell carcinoma (MCC) tissue microarray (TMA) was either immunostained with (A) a combination of PAb416, Xt7, and 2t2 or with (B) CM2B4. The same Merkel cell polyomavirus–positive (MCV-positive) (middle row) and -negative (bottom row) MCC case samples from each slide are shown for both stainings. Original magnification, ×40 (middle and bottom); ×1 (top). (C) Representative examples for passenger infection cases observed in lung squamous cell carcinoma (ca) and bladder transitional cell ca (brown). Original magnification, ×40.
