Anti-CD3E Antibody

Offered by Antibodies.com as part of the Primary Antibodies catalogue, this rabbit polyclonal reagent targets the CD3E antigen and is supplied as a 50 µl aliquot at 1.0 mg/mL in PBS (without Mg²⁺/Ca²⁺), pH 7.4, with 150 mM NaCl, 0.02% sodium azide, and 50% glycerol as a stabiliser. The antibody was raised against recombinant human CD3E protein and subsequently affinity-purified on the immunogen, ensuring selective recognition of the endogenous full-length target in samples of human, mouse, and rat origin. It is unconjugated, allowing researchers to pair it freely with secondary detection reagents or custom labels, and the polyclonal format provides a broad epitope coverage that can be advantageous when working with denatured or partially degraded antigens. Validated applications include Western blotting, immunohistochemistry, and immunofluorescence, all of which are supported by representative data images on the product page. For routine handling, vials are shipped at 4 °C and should be aliquoted upon arrival and stored long-term at −20 °C, with repeated freeze/thaw cycles avoided to preserve activity. The reagent is intended for research use only and is not cleared for diagnostic or therapeutic applications.
