Catumaxomab (anti-CD3&EpCAM), a trifunctional IgG2 antibody, is composed of mouse and rat heavy and light chains and binds to human EpCAM and human CD 3 receptors. The Fc region of Catumaxomab (anti-CD3&EpCAM) region has binding affinity for FcγR1 (CD 64), FcγRIIA (CD 32a), and FcγRIII (CD 16). Catumaxomab (anti-CD3&EpCAM) can be used for anti-tumor research, especially epithelial cancers. Purity ≥90% (SDS-PAGE&SEC) Endotoxin Level ≤1.0EU/mg Protein Function CD3: The CD3 complex mediates signal transduction. EpCAM:May act as a physical homophilic interaction molecule between intestinal epithelial cells (IECs) and intraepithelial lymphocytes (IELs) at the mucosal epithelium for providing immunological barrier as a first line of defense against mucosal infection. Plays a role in embryonic stem cells proliferation and differentiation. Up-regulates the expression of FABP5, MYC and cyclins A and E
