Recombinant humanized (from mouse) antibody expressed in CHO binding to human IgE Fc. Talizumab is a humanized monoclonal antibody as a new-concept therapeutic for allergic diseases. The unique anti-IgE antibody was designed to target immunoglobulin E (IgE) and IgE-expressing B lymphocytes specifically, without binding to IgE already bound by the high affinity IgE receptors on mast cells and basophils.

BACKGROUND
Introduction
Immunoglobulin E (IgE) is a class of antibody (or immunoglobulin (Ig) "isotype") that has been found only in mammals. IgE exists as monomers consisting of two heavy chains (ε chain) and two light chains, with the ε chain containing 4 Ig-like constant domains (Cε1-Cε4). IgE's main function is immunity to parasites such as parasitic worms like Schistosoma mansoni, Trichinella spiralis, and Fasciola hepatica. IgE may also be important during immune defense against certain protozoan parasites such as Plasmodium falciparum.
