Fig. S2B compared to C). H &E staining of the respective tissues (e.g. Suppl Fig. S2D and E) confirmed the identities of the tumor and normal tissues. Staining the biopsied (macroscopically) supposedly tumor-free tissues at the edge of the resection cavity with QD-MAb528 EGFR revealed the presence of remaining tumor cells not detected at the resolution of the enhanced MRI image in one of these tissue specimens as shown in Figure 3E (compare to 3D) and confirmed by post processing H&E staining. Here, EGFR is linked to neoplasm.
