Bleselumab
Based on 1 Customer Validation
Bleselumab (ASKP 1240) is a human anti-CD40 monoclonal antibody (mAb). Bleselumab binds to human CD40 with high affinity (Kd: 0.24 nM). Bleselumab inhibits immune responses by blocking the interaction of CD40 with its ligand CD40L. Bleselumab prevents organ transplant rejection.
