Immunohistochemistry for 7B2 in normal and unaffected liver compared to colorectal (CRC) liver metastases. A. Light microscopy 7B2 immunohistochemistry of normal liver (N), using 400 × magnification. No positive cells were identified. B. Light microscopy 7B2 immunohistochemistry of liver metastasis (T) and adjacent unaffected parenchyma (U), using 100 × magnification. Arrowheads indicate positively stained cells uniquely in the metastasis. C. Light microscopy 7B2 immunohistochemistry of liver metastasis (T) using 400 × magnification. Arrowheads indicate dense positively stained tumor cells.
