Applications

Recommended Concentration
Sample
Western Blot
0.1 µg/mL
See below
Neutralization
Measured by its ability to neutralize IL‑6 R alpha -mediated inhibition of proliferation in the M1 mouse myeloid leukemia cell line. The Neutralization Dose (ND50) is typically 0.2-0.4 µg/mL in the presence of 30 ng/mL Recombinant Human IL‑6 R alpha and 30 ng/mL Recombinant Human IL‑6.

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.

Detection of Recombinant Human
IL‑6 R alpha by Western Blot.
Western blot shows 5 ng of Recombinant Human IL‑6 R alpha (Catalog # 227-SR), Recombinant Mouse
IL‑6 R alpha (Catalog # 1830-SR) and Recombinant Rat IL-6 R. PVDF Membrane was probed with 0.1 µg/mL of Goat Anti-Human IL‑6 R alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-227-NA) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for IL‑6 R alpha at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.

IL‑6 R alpha  Enhancement of IL‑6‑dependent Inhibition of Cell Proliferation and Neutralization by Human IL‑6 R alpha  Antibody.

Recombinant Human IL‑6 R alpha (Catalog # 227‑SR) enhances Recombinant Human IL‑6 (Catalog #
206‑IL) inhibition of proliferation in the M1 mouse myeloid leukemia cell line in a dose-dependent manner (orange line). Enhancement of Recombinant Human IL‑6 (30 ng/mL) activity elicited by Recombinant Human IL‑6 R alpha (30 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL‑6 R alpha Antigen Affinity-purified Polyclonal Antibody (Catalog #
AF‑227‑NA). The ND50 is typically 0.2‑0.4 µg/mL.

Background: IL-6 R alpha

The multi-functional factor interleukin 6 (IL-6) exerts its activities through binding to a high-affinity receptor complex consisting of two membrane glycoproteins: an 80 kDa component receptor that binds IL-6 with low affinity (IL-6 R alpha ) and a signal-transducing component of 130 kDa (gp130) that does not bind IL-6 by itself, but is required for high-affinity binding of IL-6 by the complex. Both components of the receptor complex, IL-6 R alpha and gp130 have been cloned, sequenced, and expressed (1-4).

A soluble form of the IL-6 R alpha has been found in the urine of healthy adult humans (5). This soluble receptor apparently arises from proteolytic cleavage of membrane-bound IL-6 R alpha and is about 50kDa in size. No naturally-occurring mRNA encoding a truncated form of the IL-6 R alpha has been reported. Soluble forms of human and murine IL-6 R alpha s have been constructed, however, by insertion of termination codons into the regions of the IL-6 R alpha cDNAs encoding the external portions of the receptors and prior to the transmembrane domains. These soluble receptors have been expressed in COS-7 and CHO cells and have been shown to bind to IL-6 in solution and to augment the activity of IL-6 as a result of the binding of the IL-6/IL-6 R alpha complex to membrane-bound gp130 (6, 7).
