Anti-S1PR3 Antibody

S1PR3 (Sphingosine-1-Phosphate Receptor 3) is a G protein-coupled receptor that transduces signals from the bioactive lipid sphingosine-1-phosphate and has been implicated in endothelial barrier regulation, immune cell trafficking, vascular maturation, and cardiac development. This rabbit polyclonal antibody, supplied by Antibodies.com as a 100 µl unconjugated aliquot, was raised against the human receptor and validated for Western blot and immunohistochemistry workflows. Researchers can use it to probe endogenous receptor levels in cell lysates, to characterize expression in formalin-fixed paraffin-embedded tissue sections, or to map localization in vascular, immune, and neural samples. The unconjugated format allows pairing with HRP-, biotin-, or fluorophore-conjugated secondaries for chromogenic, fluorescent, or chemiluminescent detection. Cited applications include studies of angiogenesis, inflammatory signaling, and cardiovascular biology, and the reagent is intended for research use only.
