Human IL-2 R beta Antibody Summary

Species Reactivity

Human

Specificity

Detects human IL-2 R beta in direct ELISAs. In direct ELISAs, no cross-reactivity with recombinant human (rh) IL‑2 R alpha, rh gamma _c, rhIL‑4 R, or rhIL‑6 R is observed.

Source

Monoclonal Mouse IgG1 Clone # 27302

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. See Certificate of Analysis for details.
*Small pack size (-SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Applications

Recommended Concentration

Sample

Flow Cytometry

2.5 µg/10⁶ cells

Human whole blood CD56⁺ natural killer cells

Immunohistochemistry

8-25 µg/mL

See below

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Neutralization

Measured by its ability to neutralize IL‑2-induced proliferation in the MO7e human megakaryocytic leukemic cell line. Avanzi, G. et al. (1988) Br. J. Haematol. 69:359. The Neutralization Dose (ND₅₀) is typically 0.05-0.15 µg/mL in the presence of 30 ng/mL Recombinant Human IL‑2.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

IL‑2 R beta in Human Lymph Node. IL‑2 R beta was detected in immersion fixed frozen sections of human lymph node using 15 µg/mL Mouse Anti-Human IL‑2 R beta Monoclonal Antibody (Catalog # MAB224) overnight at 4 °C. Tissue was stained (red) and counterstained with hematoxylin (blue). View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Neutralization

Cell Proliferation Induced by IL‑2 and Neutralization by Human IL‑2 R beta Antibody. Recombinant Human IL-2 (Catalog # 202-IL) stimulates proliferation in the MO7e human megakaryocytic leukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL-2 (30 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IL-2 R beta Monoclonal Antibody (Catalog # MAB224). The ND₅₀ is typically 0.05-0.15 µg/mL.

Background: IL-2 R beta

Functional IL-2 receptors can exist in two affinity states on cell surfaces, the high affinity complex consisting of heterotrimers of the alpha, beta, and gamma chains and the intermediate affinity complex comprising heterodimers of the beta and gamma chains. Individual beta chains and alpha chains exhibit low affinity IL-2 binding, and the gamma chain alone does not bind IL-2. In addition to their involvement in IL-2 mediated signal transduction, both the beta chain and gamma chain have been shown to be required for IL-15 mediated signaling. IL-2 R beta is a member of the cytokine receptor superfamily. Human IL-2 R beta cDNA encodes a 551 amino acid (aa) precursor Type I membrane protein with a 26 aa signal peptide, a 214 aa extracellular region, a 25 aa transmembrane region and a 286 aa cytoplasmic domain. A soluble IL-2 R beta has been identified in the culture supernatants of a human lymphoid cell line, YT, that displays IL-2 R beta. Soluble IL-2 R beta binds IL-2 with low affinity and is not an effective IL-2 antagonist on cells displaying the high or intermediate affinity IL-2 signaling receptors. Nevertheless, soluble IL-2 R beta binds IL-15 with sufficient affinity to neutralize IL-15 biological activities.
