Omalizumab antibody | AbD20760_hIgG1



Human anti Omalizumab (Drug/Target Complex):HRP
Anti-omalizumab drug-target complex antibody specifically recognizes the omalizumab-hIgE complex exclusively and detects omalizumab or biosimilars only when bound to human IgE. This antibody is in full IgG1 format and is suitable for a PK antigen capture format assay to detect bound drug.

Clone AbD20760_hIgG1 can be used to develop a pharmacokinetic (PK) antigen capture assay to measure omalizumab captured via immobilized human IgE or to measure the level of drug/IgE complex in preclinical or clinical samples. This product is in a full immunoglobulin format and is available directly labeled with HRP. The antibody is also available in unlabeled Fab format (HCA238).
Omalizumab (brand name Xolair®) is a recombinant DNA-derived humanized IgG1 kappa monoclonal antibody used in the treatment of patients with moderate or severe asthma who have demonstrated a positive allergy skin test and whose symptoms are not controlled by inhaled corticosteroids.
Allergic asthma is mediated by IgE released by B cells in response to allergen. Circulating IgE binds to the high-affinity IgE Fc receptor (FcεRI) expressed on basophils and mast cells, triggering the release of histamine, leukotrienes and other mediators associated with the pathophysiology of asthma. Omalizumab is directed against the Fc region of human immunoglobulin E (IgE). By binding to circulating IgE at the site of FcεRI binding, this therapeutic antibody prevents the interaction of IgE with its receptor thus limiting mediator release. Treatment with omalizumab has also been demonstrated to reduce the expression of FcεRI on mast cells and basophils, providing additional clinical benefit.
