Human Anti-Dupilumab Antibody, clone AbD47091 is a paratope specific, inhibitory anti-idiotypic antibody (Type 1) that specifically recognizes the free human monoclonal antibody Dupilumab. TZA014 neither recognizes free IL-4Ra nor dupilumab in complex with IL-4Ra. Consequently, this antibody can be used to measure free dupilumab levels in serum from patients.

Anti-Dupilumab monovalent Fab antibody, TZA014, can also be converted by the user into alternative antibody formats using any of the SpyCatchers available in our catalog.

Dupilumab (Dupixent) is a human IgG4/kappa antibody inhibiting both IL‐4 and IL-13 receptors, thereby blocking these receptor signaling pathways. Dupilumab inhibits the signaling of interleukins (IL) that induce inflammatory and immunological reactions in several atopic or allergic conditions, such as eczema, allergic reaction, and rhinosinusitis.
