The purified format of this antibody can be used in conjunction with biotinylated goat anti-rat Ig (with no cross-reactivity to mouse Ig) (Cat. No. 554014) and Streptavidin-phycoerythrin (Cat. No. 554061) in a three later staining procedure to amplify immunofluorescent signals for the flow cytometric analysis of cytokine receptor-expressing cells.

This antibody has been reported to be useful for immunoprecipitation of CD122. Please note that this application is not routinely tested at BD Biosciences Pharmingen.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

The 5H4 antibody monoclonal antibody specifically binds to mouse CD122. CD122 is a 70-85 kDa type I transmembrane glycoprotein of the hematopoietin receptor superfamily. CD122 is also known as IL-2 Receptor beta chain (IL-2Rβ) or IL-15 Receptor beta chain (IL-15Rβ) as it helps form signaling receptor complexes for Interleukin-2 (IL-2) or IL-15, respectively. CD122 can combine with either CD132 (γc) alone or CD132 plus CD25 (IL-2Rα) to form intermediate or high-affinity IL-2 Receptor complexes, respectively. The IL-2R β chain is constitutively expressed on NK cells and at lower levels on some thymocytes, T cells, B cells, monocytes, and macrophages. IL-2R β chain expression is upregulated by IL-2. The immunogen used to generate this hybridoma was rat myeloma cells transfected with a truncated IL-2R β cDNA. 5H4 does not block IL-2 binding to the IL-2 Receptor.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
