DOTA-Bn-CA-170

DOTA-Bn-CA-170 is a molecular probe targeting the VISTA protein, with a Kd value of 0.124 nM. DOTA-Bn-CA-170 is formed by covalently linking the p-SCN-Bn-DOTA ligand with CA-170. DOTA-Bn-CA-170 labeled with [68Ga]Ga successfully achieves specific and high-contrast PET imaging of VISTA expression in various tumor-bearing mouse models. DOTA-Bn-CA-170 can be used for the study of VISTA-targeted immunotherapy[1].
