Specificity

Detects human Common gamma Chain/IL-2 R gamma in direct ELISAs and Western blots. In direct ELISAs, no cross-reactivity with recombinant human (rh) IL-2 R alpha, rhIL-2 R beta, rhIL-15 R alpha, recombinant mouse IL-2 R gamma, or recombinant canine IL-2 R alpha is observed. In Western blots, approximately 80% cross-reactivity with recombinant human IL-2 R beta, 50% cross-reactivity with rhIL-15 R alpha and recombinant mouse IL-2 R alpha, and no cross-reactivity with rhIL-2 R alpha is observed.

Scientific Data Images for Human Common gamma Chain/IL‑2 R gamma Antibody

Detection of Common gamma Chain/IL‑2 R gamma in Human PBMC by Flow Cytometry.

Human peripheral blood lymphocytes were stained with Mouse Anti-Human Common gamma Chain/IL-2 R gamma Monoclonal Antibody (Catalog # MAB2842, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG F(ab')₂Secondary Antibody (Catalog # F0101B).

Cell Proliferation Induced by IL‑2 and Neutralization by Human Common gamma Chain/ IL‑2 R gamma 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 Recom-binant Human IL-2 (200 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human Common gamma Chain/IL-2 R gamma Monoclonal Antibody (Catalog # MAB2842). The ND₅₀ is typically 0.08-0.4 µg/mL.

Applications for Human Common gamma Chain/IL‑2 R gamma Antibody

Application

Recommended Usage

CyTOF-ready

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

Flow Cytometry

2.5 µg/10⁶ cells
Sample: Human peripheral blood lymphocytes

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 0.08-0.4 µg/mL in the presence of 200 ng/mL Recombinant Human IL‑2.

Background: Common gamma Chain/IL-2 R gamma

The gamma chain of the high affinity functional human IL-2 receptor complex belongs to the hematopoietin receptor family. IL-2 R gamma is a 369 amino acid protein consisting of a 22 aa signal sequence, a 232 aa extracellular domain, a 29 aa transmembrane domain and an 86 aa cytoplasmic domain. Although IL-2 R gamma by itself does not bind IL‑2 with any appreciable affinity, it is required for IL-2 receptor signaling. Besides IL-2, the gamma chain has been shown to be a component of the functional receptor complexes for IL-4, IL-7, IL-9 and IL-15. IL-2 R gamma has been designated the common gamma chain ( gamma _c). The site of molecular defects in X-linked SCID (severe combined immunodeficiency) has been mapped to the IL-2 R gamma gene.
