Fig. 3From: Expression of truncated human epidermal growth factor receptor 2 on circulating tumor cells of breast cancer patientsHER2 full-length and truncated HER2 expression on CTCs of breast cancer patients. Representative Ariol system images from one metastatic patient expressing both (a) CTCs with truncated HER2 receptor after triple-staining with HER2 (ICD), HER2 (ECD) and pancytokeratin (A45-B/B3) antibodies and (b) CTCs with full length receptor.
