Product Details


This Rat Interleukin 6 (IL-6) ELISA Kit is suitable for qualitatively determining IL-6 concentrations in muliple biological fluids, including rat serum, plasma, and tissue homogenates in vitro. IL-6 is a pleiotropic pro-inflammatory cytokine, and its production is responsive to tissue injury and infections. It is involved in diverse biological processes such as the modulation of the host immune response, the progression of several virus infectons, and the regulation of immune cell proliferation and differentiation. IL-6 exerts its biological roles through a hexameric complex IL-6/IL-6R/gp130, which activates different signaling pathways such as JAK/STAT3, Ras/MAPK, PI3K–PKB/Akt to execute various biochemical functions. Deregulation of IL-6 signaling is associated with chronic inflammation, and multifactorial auto-immune disorders.

This kit uses the quantitative sandwich-based enzyme immunoassay technique to measure the amount of rat IL-6 in the sample. Standards and samples are respectively added to the microplate wells pre-coated with anti-rat IL-6 antibody. Biotin-labeled IL-6 antibody, HRP-avidin, TMB substrate are pipped into the microplate in turn. The capture antibody pre-coated on the plate captures the IL-6 in the rat samples. IL-6 binds to the biotinylated anti-rat IL-6 monoclonal antibody. And the biotin on the biotinylated anti-rat IL-6 monoclonal antibody binds to the avidin on the enzyme label, forming immune complexes. The color renders blue after the addition of TMB substrate. The addition of stop solution into the wells immediately turns the blue into yellow. The concentration of IL-6 in the samples is directly proportional to OD (450nm). Each manufactured lot of this ELISA kit was quality tested for criteria such as sensitivity, specificity, and lot-to-lot consistency. See manual for more information on validation.

Target Background

(From Uniprot)
Cytokine with a wide variety of biological functions. It is a potent inducer of the acute phase response. Plays an essential role in the final differentiation of B-cells into Ig-secreting cells Involved in lymphocyte and monocyte differentiation. Acts on B-cells, T-cells, hepatocytes, hematopoietic progenitor cells and cells of the CNS. Required for the generation of T(H)17 cells. Also acts as a myokine. It is discharged into the bloodstream after muscle contraction and acts to increase the breakdown of fats and to improve insulin resistance. It induces myeloma and plasmacytoma growth and induces nerve cells differentiation (By similarity).
