CD3 epsilon (CD3E) serves as an essential component of the T cell receptor complex, playing a fundamental role in T cell development, activation, and signal transduction. As part of the CD3 signaling module, this surface glycoprotein is indispensable for proper immune function, making it a critical marker for T cell identification and a key target in immunology research spanning from basic T cell biology to immunotherapy development.
This recombinant monoclonal antibody, clone 25E11, offers the consistency and reliability that demanding experimental workflows require. Produced using recombinant technology, each lot delivers sequence-defined specificity against human CD3E, eliminating the batch-to-batch variability that can complicate longitudinal studies or multi-site collaborations. The mouse IgG2a isotype and affinity-chromatography purification ensure a clean, well-characterized reagent suitable for sensitive detection applications.
Validation studies demonstrate robust performance in flow cytometry applications using the Jurkat cell line (JK cells), a well-established human T cell leukemia model that endogenously expresses CD3E. Surface staining at 1:100 dilution produced clear positive signal separation from isotype control, with recommended working dilutions ranging from 1:20 to 1:500 providing flexibility to optimize detection sensitivity for your specific experimental conditions. The antibody is also validated for ELISA applications, expanding its utility across different experimental platforms.
Whether you are characterizing T cell populations, investigating TCR signaling pathways, or exploring stem cell differentiation toward T cell lineages, this CD3E antibody provides a dependable tool for human sample analysis. The liquid format with glycerol-based buffer supports convenient aliquoting and long-term storage stability at -20°C or -80°C.
