Used in immunological research to inhibit IDO2 (indoleamine 2,3-dioxygenase 2) enzyme activity, this antibody helps modulate immune responses in experimental models. It is applied in studies related to autoimmune diseases, cancer immunotherapy, and inflammation to understand the role of IDO2 in immune tolerance and suppression. Due to its specificity, it serves as a reference tool for validating IDO2 expression and function in cell-based assays and tissue samples. It is also utilized in preclinical development to assess potential therapeutic strategies targeting the IDO2 pathway.
