Human Common  gamma  Chain/IL-2 R gamma Antibody Summary

Species Reactivity
Human
Specificity
Detects human Common  gamma  Chain/IL‑2 R gamma in direct ELISAs and Western blots. In direct ELISAs, approximately 50% cross-reactivity with recombinant mouse IL-2 R gamma is observed, less than 10% cross-reactivity with recombinant human (rh) IL-2 R beta is observed, and less than 2% cross-reactivity with rhIL-2 R alpha is observed.

Applications

Recommended Concentration
Sample
Western Blot
0.1 µg/mL
Recombinant Human Common  gamma  Chain/IL‑2 R gamma (Catalog # 384-RG)
Flow Cytometry
0.25 µg/106 cells
Daudi human Burkitt's lymphoma cell line
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 20-60 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.

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 Goat Anti-Human Common  gamma  Chain/
IL‑2 R gamma Antigen Affinity-purified Polyclonal Antibody (Catalog # AF284). The ND50 is typically 20-60 µg/mL.

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 residue protein consisting of a 22 residue signal sequence, a 232 residue extracellular domain, a 29 residue transmembrane domain and an 86 residue 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. It has been proposed that IL-2 R gamma be designated the common gamma chain ( gamma c). The site of molecular defects in X-linked SCID (severe combined immunodeficiency) has now been mapped to the IL-2 R gamma gene.
