| Bioactivity | MDX-1342 is a fully human monoclonal antibody (HuMAb) of targeting CD19-membrane receptor. MDX-1342 can specifically bind to human CD19 antigen with high affinity and has antibody-dependent cellular cytotoxicity (ADCC) effect. MDX-1342 can be used for the research of B-lymphocyte malignancies and autoimmune[1]. |
| Target | EC50 for binding activity: 0.34 μg/mL(Ramos cells); 0.47 μg/mL(Raji cells); 0.74 μg/mL(ARH-77 cells); 0.37 μg/mL(FcyRIIIa-Val158 transfected cells); 1.18 μg/mL(FcyRIIIaPhe158 transfected cells) |
| Invitro | MDX-1342 (0-100 μg/mL; 30 min) shows binding activity for Ramos, Raji, and ARH-77 cells with EC50 values of 0.34, 0.47, and 0.74 μg/mL, respectively[1].MDX-1342 (0-100 μg/mL; 30 min) shows binding activity for FcyRIIIa-Val158 and FcyRIIIaPhe158 transfected cells with EC50 values of 0.37 and 1.18 μg/mL, respectively[1].MDX-1342 (0-100 μg/mL) has robust antibody-dependent cellular cytotoxicity (ADCC) with an average EC50 value of 0.01-0.02 ug/mL[1].MDX-1342 (0-100 μg/mL) mediates dose-dependent phagocytosis of ARH-77 cells by macrophages[1]. Cell Viability Assay[1] Cell Line: |
| In Vivo | MDX-1342 (i.v.; 0.03, 0.3, 3 and 30 mg/kg; 200 μL) shows dose-dependent improvement in survival using a murine B-cell lymphoma model[1]. MDX-1342 (i.v.; 0.1 or 1 mg/kg; single) has low nanomolar binding to cynomolgus monkey CD19, increases affinity for cynomolgus monkey FcyRllla and reveals potent B-cell depletion in vivo[1].
