Background Information
CD3 is a multimeric protein associated with the T-cell receptor (TCR) to form a complex involved in antigen recognition and signal transduction (PMID: 15885124). CD3 is composed of CD3γ, δ, ε, and ζ chains (PMID: 1826255). It is expressed by thymocytes in a developmentally regulated manner, T cells, and some NK cells (PMID: 3289580). The TCR recognizes antigens bound to major histocompatibility complex (MHC) molecules. TCR-mediated peptide-MHC recognition is transmitted to the CD3 complex, leading to the intracellular signal transduction (PMID: 11985657).

FH Daniel (Verified Customer) (11-28-2025) | We used this antibody to determine whether CD3 was present on our macrophage cell line, and are happy to report that it could be found. Hopefully this will now lead to further understanding of immune mechanisms in host response against bacterial pathogens.
