Recommended Concentration
Sample
Western Blot
1 µg/mL
Recombinant Human IL‑6 (Catalog # 206-IL)
Simple Western
50 µg/mL
PBMC conditioned media
Neutralization
Measured by its ability to neutralize IL‑6-induced proliferation in the T1165.85.2.1 mouse plasmacytoma cell line [Nordan, R.P. and M. Potter (1986) Science 233:566]. The Neutralization Dose (ND50) is typically 0.05-0.15 µg/mL in the presence of 2.5 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.

Neutralization Cell Proliferation Induced by IL‑6 and Neutralization by Human IL‑6 Antibody. View Larger

Cell Proliferation Induced by IL‑6 and Neutralization by Human IL‑6 Antibody. Recombinant Human IL-6 (Catalog # 206-IL) stimulates proliferation in the T1165.85.2.1 mouse plasmacytoma cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL-6 (2.5 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL-6 Polyclonal Antibody (Catalog # AB-206-NA). The ND50 is typically 0.05-0.15 µg/mL.

Simple Western View Larger

Detection of Human IL‑6 by Simple WesternTM. Simple Western lane view shows PBMC conditioned media untreated (-) or treated (+) with PHA, loaded at 0.2 mg/mL. A specific band was detected for IL‑6 at approximately 31 kDa (as indicated) using 50 µg/mL of Goat Anti-Human IL‑6 Polyclonal Antibody (Catalog # AB-206-NA). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: IL-6

Interleukin-6 (IL-6) is a pleiotropic, alpha -helical, phosphorylated and variably glycosylated cytokine that plays important roles in the acute phase reaction, inflammation, hematopoiesis, bone metabolism, and cancer progression. Mature human IL-6 is 183 amino acids (aa) in length expressed as a 22-28 kDA molecular weight protein. IL-6 shares 39% aa sequence identity with mouse and rat IL-6. Alternative splicing generates several isoforms with internal deletions, some of which exhibit antagonistic properties. IL-6 induces signaling through a cell surface heterodimeric receptor complex composed of a ligand binding subunit (IL-6 R alpha) and a signal transducing subunit (gp130). IL-6 binds to IL-6 R alpha, triggering IL-6 R alpha association with gp130 and gp130 dimerization. gp130 is also a component of the receptors for CLC, CNTF, CT-1, IL-11, IL-27, LIF, and OSM. Soluble forms of IL-6 R alpha are generated by both alternative splicing and proteolytic cleavage. In a mechanism known as trans-signaling, complexes of soluble IL-6 and IL-6 R alpha elicit responses from gp130-expressing cells that lack cell surface IL-6 R alpha. Trans-signaling enables a wider range of cell types to respond to IL-6, as the expression of gp130 is ubiquitous, while that of IL-6 R alpha is predominantly restricted to hepatocytes, monocytes, and resting lymphocytes. Soluble splice forms of gp130 block trans-signaling from IL-6/IL-6 R alpha but not from other cytokines that use gp130 as a co-receptor. IL-6, along with TNF-alpha and IL-1, function to drive the acute inflammatory response and the transition from acute inflammation to either acquired immunity or chronic inflammatory disease. When dysregulated, it contributes to chronic inflammation in obesity, insulin resistance, inflammatory bowel disease, arthritis, sepsis, and atherosclerosis. IL-6 can also function as an anti-inflammatory molecule, as in skeletal muscle where it is secreted in response to exercise. In addition, it enhances hematopoietic stem cell proliferation and the differentiation of Th17 cells, memory B cells, and plasma cells.
