In vivo antibodies delivery efficacy of NCPA. A) Ex vivo fluorescence images of aCD47 and aPD‐L1 in tumors and major organs were collected from mice after 24 h intravenous injection. B) Semi‐quantitative mean fluorescence intensity analysis of ex vivo major organs and tumor. C) Representative images of CD206/CD47/PD‐L1 expression in LLC tissue. D) Confocal images of tumor frozen sections and (E&F) fluorescence intensity analysis of E) free antibody combination CPA and F) NCPA, the aCD47 was stained green with CY3 and the aPD‐L1 was stained red with CY5. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001.
