Bio-Rad, HCA426, Benralizumab antibody | AbD60095ia

Human Anti-Benralizumab Antibody, clone AbD60095ia is a paratope specific, anti-idiotypic antibody (Type 1) that specifically recognizes the free human monoclonal antibody drug benralizumab. It does not recognize the drug target, human interleukin 5 receptor α (IL5Rα), nor benralizumab in complex with IL5Rα. HCA426 is a fully human recombinant monoclonal antibody with IgG1 isotype and is suitable as a surrogate positive control or calibrator in an anti-drug antibody (ADA) assay. This antibody has a monovalent intrinsic affinity of 0.2nM and is one of the three antibodies offered for ADA assays. Antibody HCA427 has an affinity of 4nM and HCA428 has an affinity of 6nM. Benralizumab (trade name Fasenra) is a humanized monoclonal antibody of the IgG1/kappa isotype that binds with high affinity to a conformationally distinct epitope within domain 1°F the α-chain of IL-5R, and thus inhibits proliferation of IL-5-dependent cell lines, and otherwise blocks signaling through the IL-5 receptor. Benralizumab is indicated as a maintenance treatment for severe asthma and an eosinophilic phenotype. View a summary of all anti-benralizumab antibodies
