Anti-CD229 Antibody

CD229, also designated LY9 or SLAMF3, is a homophilic cell-surface receptor of the SLAM immunoglobulin superfamily expressed predominantly on T and B lymphocytes, where it modulates lymphocyte adhesion and activation through SAP-dependent signaling. Produced and quality-controlled by Antibodies.com, this unconjugated rabbit polyclonal reagent is raised against human CD229 and validated for Western blot and ELISA workflows. Supplied as 100 µl of polyclonal antiserum in a vial, the antibody supports flexible assay development for studies of lymphoid signaling, immune synapse formation, and characterization of T- and B-cell maturation stages in research samples. Researchers investigating lymphocyte activation pathways, innate-like T-cell biology, or SLAM-family receptor interactions can incorporate this reagent into standard immunoblotting and antigen-detection protocols.
