CD274 and neoplasm: Moreover, PmTriTNE@CDA pretreated at pH 6.5 showed higher levels of tumor cell binding than mPEG‐HA‐PAMAM@CDA pretreated at pH 6.5 and mPEG‐HA‐PD‐L1‐PAMAM@CDA pretreated at pH 6.5, which suggested that dual targeting could increase the binding affinity and selectivity (Figure 1H,I).
