Target/Specificity Mouse anti-Human CD3 (MEM-57) is a monoclonal antibody recognizing an extracellular epitope of the human CD3 complex containing either δ-ε or γ-ε subunit complexes (Daveet al.1997). Mouse anti-Human CD3 (MEM-57) recognizes a conformational CD3 epitope minimally requiring the presence of the CD3ε subunit (Transyet al.1989) as it will recognize murine 3D054.8 hybridoma cells tranfected with cDNA to express the human CDε subunit lacking its cytoplasmic domain. CD3 serves as a pan T cell marker, it is expressed on the surface of over 95% of circulating human peripheral T cells. CD3 is also present on ~60-80% of thymocytes and on Purkinji cells, neurons present in the cerebellar cortex. CD3 is not expressed on B cells or NK cells. The TCR complex consists of TCR heterodimers, either α/β or γ/δ expressed in a mutually exclusive manner, analagous that seen in mice on different T cell lineages. In order for the TCR heterodimer to be expressed on the cell surface it must associate with a minimal CD3 complex. The CD3 complex itself is made up of four subunits, γ, δ, ε and ζ responsible for effecitng signalling upon TCR activation, via a single or multiple, depending on the subunit, immunoreceptor tyrosine-based activation motif (ITAM) present in the CD3 subunit cytoplasmic domain (Kuhnset al.2006Daveet al.1997).Mouse anti-Human CD3 clone MEM-57 demonstrates a mitogenic effect on peripheral blood T cells and on the lymphoblastoid Jurkat cell line (Batistaet al.2004Brdickováet al.2003). Clone MEM-57 immunoprecipitates proteins of ~22 kDa and more weakly ~28 kDa. from peripheral blood T cell lysates.
