    Recommended
    Concentration
    Sample
  • Western Blot
    0.1 µg/mL
    Recombinant Cotton Rat IL‑6 (Catalog # 561-R6)
  • 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 0.03-0.12 µg/mL in the presence of 0.25 ng/mL Recombinant Cotton Rat 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.
Data Examples
Cell Proliferation Induced by IL‑6 and Neutralization by Cotton Rat IL‑6 Antibody.

Recombinant Cotton Rat IL‑6 (Catalog # 561-R6) stimulates proliferation in the T1165.85.2.1 mouse plasmacytoma cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Cotton Rat IL‑6 (0.25 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Cotton Rat IL‑6 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF561). The ND50 is typically 0.03‑0.12 µg/mL.

Background: IL-6

Interleukin 6 (IL-6) is a pleiotropic alpha -helical cytokine that plays important roles in acute phase reactions, inflammation, hematopoiesis, bone metabolism, and cancer progression. IL-6 activity is central to the transition from acute inflammation to either acquired immunity or chronic inflammatory disease. It is secreted by multiple cell types as a 22 kDa‑28 kDa phosphorylated and variably glycosylated molecule (1‑4). Mature cotton rat IL-6 is 186 amino acids (aa) in length and shares 39%, 70%, and 75% aa sequence identity with human, mouse, and rat IL-6 (5). IL-6 induces signaling through a cell surface heterodimeric receptor complex composed of a ligand binding subunit (IL-6 R) and a signal transducing subunit (gp130). IL-6 binds to IL-6 R, triggering IL-6 R association with gp130 and gp130 dimerization (6). gp130 is also a component of the receptors for CLC, CNTF, CT-1, IL-11, IL-27, LIF, and OSM (7). Soluble forms of IL-6 R are generated by both alternate splicing and proteolytic cleavage (3). In a mechanism known as trans-signaling, complexes of soluble IL-6 and IL-6 R elicit responses from gp130-expressing cells that lack cell surface IL-6 R (3). 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 is predominantly restricted to hepatocytes, leukocytes, and lymphocytes (3). Soluble splice forms of gp130 block trans-signaling from IL-6/IL-6 R but not from other cytokines that utilize gp130 as a coreceptor (4, 8).
