Synthetic peptide from the intracellular part of the e-chain of human CD3 was coupled to bovine thyroglobulin and used for immunization. The antibody is a pan-T cell marker for identification of T cells. It is well-suited for labeling reactive T cells in tissue with lymphoid infiltrates, and for classification of T-cell neoplasms. The antibody shows a stronger labeling intensity than corresponding monoclonal antibodies to CD3, and should, generally, be preferred on formalin-fixed, paraffin-embedded tissue sections.

Autostainer Link 48
In Western blotting, the antibody detects bands of the expected molecular weights for CD3 antigens (2). The antibody recognizes CD3e in both a T-cell line (Jurkat) and a natural killer cell line (NK11), but does not react with lysates prepared from several B-cell lines (Raji, Ramos and JY), a myeloid cell line (U937) or a colon carcinoma cell line (Colo-205) (9).
In immunoprecipitation from Nonidet P40 lysates of surface-iodated T lymphoblasts, the antibody precipitates the γ (26 kDa), δ (21 kDa) and e (19 kDa) chain of the CD3 molecule, similar to the precipitation pattern seen using the well-characterized monoclonal mouse anti-human CD3, clone UCHT1 (1).
In ELISA, the antibody labels the CD3 peptide used as immunogen. See package insert for reference(s).
