Neutralizing human IgG1 monoclonal antibody against human TNF-α

Anti-hTNF-α-hIgG1 is a neutralizing monoclonal antibody (mAb) featuring the constant region of the human IgG1 (hIgG1) isotype and the variable region of adalimumab, a fully human therapeutic mAb that targets human tumor necrosis factor-alpha (hTNF-α). TNF-α is a pleiotropic cytokine that notably induces NF-κB-mediated production of pro-inflammatory cytokines [1,2]. The variable region of adalimumab blocks the interaction of TNF-α with its receptors TFNR1 and TNFR2, thereby downregulating the inflammatory responses associated with autoimmune diseases, such as rheumatoid arthritis and Crohn’s disease [1,2]. The hIgG1 isotype displays a high binding-affinity for the Fc receptor on phagocytic cells, and is highly potent for Fc-mediated antibody-dependent cellular cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), and complement-dependent cytotoxicity (CDC). 

Anti-hTNF-α-hIgG1 was generated by recombinant DNA technology. It is produced in CHO cells and purified by affinity chromatography with protein G. The neutralizing activity of anti-hTNF-α-hIgG1 antibody was determined using HEK-Blue™ TNF-α cells.
