InVivoSIM bispecific anti-human CD3 x CD20 (Epcoritamab Biosimilar)
Clone
Epcoritamab
Reactivities
Human
Isotype
Human IgG1
Product Description
This Epcoritamab biosimilar antibody uses the same variable regions as the therapeutic antibody Epcoritamab, making it ideal for research use. Epcoritamab is a full-length bispecific IgG1 antibody that simultaneously targets human CD3 on T cells and human CD20 on B cells. By engaging CD3 and CD20, Epcoritamab redirects and activates T cells against malignant B cells, promoting synapse formation, T-cell activation, cytokine release, and targeted tumor-cell killing. Unlike earlier bispecific formats, this IgG-based architecture provides extended half-life, efficient T-cell engagement, and potent in vivo activity. Clinically, Epcoritamab has demonstrated significant efficacy in relapsed or refractory B-cell non-Hodgkin lymphomas, including diffuse large B-cell lymphoma (DLBCL), and works through direct T-cell–mediated cytotoxicity rather than Fc-dependent mechanisms. This Epcoritamab biosimilar is well suited for investigating T-cell redirection, CD3/CD20 synapse biology, B-cell malignancies, immune-cell cytotoxicity, and the mechanistic basis of bispecific antibody therapies.
