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.

Recombinant Human Common gamma Chain/IL‑2 R gamma (Catalog # 384-RG)
0.25 µg/106 cells
Daudi human Burkitt's lymphoma cell line
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
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.
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 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.
