Species Reactivity: All Species Expected Source / Purification Monoclonal antibody is produced by immunizing animals with an scFv derived from a murine anti-CD19 monoclonal antibody, FMC63. Background Chimeric antigen receptor (CAR) T cell therapy utilizes synthetic receptors to redirect T cells to bind and eliminate tumor cells, bypassing traditional T cell receptor (TCR) signaling (1). The extracellular domain of conventional CARs consists of single-chain variable fragments (scFvs), which recognize and bind target antigens (1). CARs engineered to express the scFv of a murine anti-CD19 antibody, FMC63, have shown clinical success in targeting CD19-expressing malignant B cells for degradation. This clinical success has led to several FMC63-based CARs being approved by the U.S. Food and Drug Administration (FDA) for the treatment of B-cell leukemia and lymphoma (2,3).
