| 应用 | Western Blot(0.1 µg/mL) |
| 目标/特异性 | Detects cotton rat IL-6 in direct ELISAs and Western blots. In direct ELISAs, approximately 20% cross‑reactivity with recombinant mouse IL-6 and recombinant rat IL-6 is observed and less than 5% cross-reactivity with recombinant porcine IL-6 and recombinant human IL-6 is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL 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. |

| R&D Systems personnel manually curate a database that contains references using R&D Systems products. The data collected includes not only links to publications in PubMed, but also provides information about sample types, species, and experimental conditions. Synergistic induction of interferon alpha through TLR-3 and TLR-9 agonists identifies CD21 as interferon alpha receptor for the B cell response. | |

| 背景 | 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). |

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. |
