Furthermore, we observed high uptake in the lesion of a patient with breast cancer, and IHC staining revealed a B7H3 expression level of B7H3 2+ (Figure 6B); however, we observed lower uptake in the lesion of a patient with lung cancer with weak B7H3 expression (B7H3 1+) (Figure 6C). Here, CD276 is linked to lung carcinoma.
