PTPRC and prostate cancer: Therefore, we analyzed the mean CD45 levels of all TRA + cells and blotted the mean CD45 intensities for TRA + cells from six healthy controls (Figure 3A, blue), six metastatic (Figure 3A, red), six localized (Figure 3A, gray) prostate cancer patients and from the one patient who progressed (Figure 3A, orange) so that each dot represents one TRA + cell.
