Anti-Ephrin-B1 (phospho-Y317) Antibody

This rabbit polyclonal antibody from Antibodies.com specifically recognizes Ephrin-B1 when phosphorylated at the tyrosine 317 residue, enabling researchers to monitor activation-dependent signaling of this membrane-anchored Eph receptor ligand. The unconjugated reagent is supplied as 100 µl of a 1 mg/ml solution in phosphate buffered saline (PBS) with 0.05% sodium azide at approximately pH 7.2, ready for direct labeling in custom detection workflows. Validated for Western blot (WB), the reagent cross-reacts with human, mouse, and rat samples, making it useful across common model systems and primary tissue studies. The polyclonal format increases the likelihood of detecting the phospho-Y317 epitope even when adjacent residues vary between species, supporting consistent recognition in comparative experiments. Sodium azide is included as a preservative, and the product ships unconjugated for flexible pairing with secondary antibodies of the researcher's choice.
