Figure 2.

This figure highlights the finding that patients with prostate cancer and BPH consistently express distinct, disease-related autoantibody reactivity to the target antigens. The top two images are from the same prostate cancer patient in duplicate runs, and the bottom two images are from the same BPH patient in duplicate runs. Circled spots show greater fluorescence, or autoantibody reactivity to the antigen, in the cancer sample than in the BPH sample.
