SubB2M-A12-SPR analysis of cancer-free and Stage I – IV breast cancer serum samples. A 22 serum samples from cancer-free females, 24 Stage I, 24 Stage II, 24 Stage III and 24 Stage IV serum samples were analyzed by SubB2M-A12-SPR assay. The mean GPUs from duplicate analyses for each serum sample are shown. Error bars = ± 1 SD from the mean for each group. Statistical analysis was performed using two-tailed unpaired t-tests. **** = P-value < 0.0001 compared to Normal. Duplicate, independent assays were performed with both showing the same trends. One representative assay is shown. Only values above 0 are shown. B Cancer-free controls compared to early stage breast cancer samples only (Stage I and II samples only from Fig. 3A). C Descriptive statistics of data from breast cancer patient serum samples and cancer-free controls
