About InVivoMAb anti-human CD3

The UCHT1 (Leu-4)(T3) monoclonal antibody reacts with human CD3ε a 20 kDa transmembrane cell-surface protein that belongs to the immunoglobulin superfamily. CD3εis one of five polypeptide chains that combine to form the TCR complex. CD3εis expressed on T lymphocytes NK-T cells and to varying degrees on developing thymocytes. CD3 plays roles in TCR signaling T lymphocyte activation and antigen recognition. Crosslinking of the TCR via immobilized UCHT1 (Leu-4)(T3) antibody is commonly used to activate T cells in vitro.
