Anti-CD3-ε Antibody

This recombinant rabbit monoclonal reagent from Antibodies.com binds the epsilon (ε) subunit of human CD3, a 20 kDa component of the T-cell receptor (TCR) complex expressed on mature T lymphocytes and on developing thymocytes. Cloned from a rabbit host and supplied unconjugated, the antibody is validated for western blot (WB), immunohistochemistry (IHC), and flow cytometry (FC) workflows against human samples, supporting T-cell phenotyping, lymphoid tissue characterization, and TCR signalling studies in immunology and translational research.

Each vial contains 100 µl of recombinant antibody formulated in TBS (pH 7.4) with 1% BSA, 40% glycerol, and 0.05% sodium azide as preservative. The recombinant production format delivers consistent batch-to-batch performance without the variability seen in polyclonal sera, while the unconjugated format lets researchers pair the reagent with HRP, biotin, or fluorophore-labelled secondary antibodies for their chosen detection method.
