Anti-ITGAE Antibody

This rabbit polyclonal reagent targets human Integrin alpha E (ITGAE), the transmembrane adhesion molecule also designated CD103. Produced by Antibodies.com as an unconjugated primary antibody, it is intended for researchers studying epithelial immune cell biology, mucosal T-cell retention, and the integrin-E-cadherin interaction in tissue sections.

The antibody is supplied as a 100 µl volume and has been validated for Western blot (WB) and immunohistochemistry (IHC) workflows on human samples. Its polyclonal format allows recognition of multiple epitopes on the ITGAE extracellular domain, supporting detection of CD103-positive intraepithelial lymphocytes and relevant dendritic subsets in fixed or lysed preparations.

Because the reagent is unconjugated, it can be paired with HRP, fluorophore, or biotin secondary reagents according to the assay read-out desired. Refrigerated storage between uses preserves activity; small aliquots are advised to limit freeze-thaw cycles when longer-term storage below -20 degrees C is needed.
