BI-836858
Based on 1 Customer Validation
BI-836858 is a fully human anti-CD33 monoclonal antibody. BI-836858 reduces CD33+ cells via antibody-dependent cellular cytotoxicity (ADCC), blocks downstream signaling of S100A9/CD33, decreases the secretion of immunosuppressive cytokines and reactive oxygen species-induced genomic instability, and restores bone marrow hematopoietic function. BI-836858 is applicable to the research of myelodysplastic syndrome (MDS) and AML.
