Anti-Blr1 Antibody

Rabbit polyclonal antiserum raised against the Burkitt lymphoma receptor 1 (Blr1), the G protein-coupled chemokine receptor now widely referenced as CXCR5. This unconjugated primary reagent from Antibodies.com is supplied as a 100 µl vial and is validated for western blot and ELISA workflows on human samples. CXCR5 directs B lymphocyte migration toward the follicular chemokine CXCL13, guiding germinal center formation, lymphoid organ homing, and T follicular helper cell positioning within secondary lymphoid tissue, which makes Blr1 a useful marker in studies of adaptive immunity, lymphoma biology, and chronic inflammatory disease. The polyclonal format allows recognition of multiple epitopes on the receptor, supporting detection across denatured and partially folded preparations. Researchers commonly deploy this antibody to confirm receptor expression in lymphoma cell lines, tonsil sections, and peripheral blood mononuclear cell lysates. The reagent is reactive with human Blr1 and does not require any secondary species cross-adsorption for standard human tissue work. Provided as a research use only reagent for investigators working on B-cell trafficking, germinal center dynamics, and CXCL13/CXCR5 axis signaling.
