Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
<0.10 EU per 1 μg of the antibody by the LAL method.
Measured by its ability to neutralize IL‑6-induced proliferation in the T118.104.22.168 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.

Cell Proliferation Induced by IL‑6 and Neutralization by Human IL‑6 Antibody.
Recombinant Human IL‑6 (Catalog # 206-IL) stimulates proliferation in the T122.214.171.124 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.

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 essential for the transition from acute inflammation to either acquired immunity or chronic inflammatory disease. It is secreted by multiple cell types as a 22-28 kDa phosphorylated and variably glycosylated molecule. Mature human IL-6 is 183 amino acids (aa) in length and shares 41% aa sequence identity with mouse and rat IL-6. Alternate splicing generates several isoforms with internal deletions, some of which exhibit antagonistic properties. Human IL-6 is equally active on mouse and rat cells. 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. 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 are generated by both alternate splicing and proteolytic cleavage. 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. 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. 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.
