From: Using in vivo fluorescence lifetime imaging to detect HER2-positive tumors
a Fluorescence lifetime and b fluorescence intensity measured in vivo at the tumor and contralateral sites, 1Â h after injection of HER2-specific Affibody probe. c HER2 expression in each tumor measured by ELISA after tumor extraction. d Immunohistology images of five different tumor types with different HER2 expression, extracted 24Â h after injection of HER2-specific affibody, and stained using DAKO HercepTestâ„¢ (Dako, Carpinteria, CA). Brown area shows HER2 positively stained cell membranes in the tumor tissue
