ANXA5 and neoplasm: To analyze fluorescence signals from the tumors and organs in the absence of antibody treatment, a separate set of tumor‐bearing mice received intravenous injections of PBS (0.1 mL; n = 4), Q‐annexin V (n = 4), and annexin V‐Alexa647 (n = 5) on day 10, and in vivo NIR fluorescence images of the mice were obtained 3 h later, as described above.
