Anti-IL-2Rβ Antibody

Raised in rabbit against the human IL-2 receptor beta subunit, also known as CD122, this unconjugated polyclonal IgG reagent from Antibodies.com is supplied as 100 µl of stock for Western blot and ELISA workflows. The antibody targets the transmembrane signaling chain shared by the intermediate- and high-affinity IL-2 receptors, enabling detection of receptor expression on activated T lymphocytes and NK cells in immunology research. Recommended storage is at -20 °C in working aliquots to preserve activity across freeze-thaw cycles, with brief bench use kept on ice. Researchers commonly apply this reagent to characterize regulatory T cell (Treg) populations, investigate cytokine-driven proliferation, and probe IL-2 and IL-15 signaling cross-talk in primary human lymphocyte cultures.
