Anti-IL-2Rβ / CD122 (Ab-364) Antibody

A polyclonal antibody from Antibodies.com raised in rabbit and affinity-purified against the human interleukin-2 receptor beta chain (IL-2Rβ, also known as CD122). Supplied unconjugated as a 100 µl liquid preparation, this reagent is validated for Western blot, immunohistochemistry, and immunofluorescence detection of CD122 on human samples. IL-2Rβ forms the signaling subunit of the high-affinity IL-2 receptor expressed on activated T lymphocytes and natural killer cells, where it contributes to proliferative and effector responses downstream of IL-2 binding. Investigators studying T cell activation, NK cell biology, and cytokine receptor signaling can apply this antibody to detect endogenous receptor distribution in cell lysates and tissue sections using standard chromogenic, fluorescent, or chemiluminescent readout systems. Each lot is supplied as a ready-to-dilute polyclonal antiserum in storage buffer, with no fluorophore or enzyme label pre-attached, allowing flexible pairing with secondary detection reagents of the researcher's choice.
