Description

Interleukin 6 (IL-6) is a multifunctional cytokine that plays important roles in immune responses, inflammation, and hematopoiesis. Originally identified as interferon beta 2, IL-6 is produced by various cell types including macrophages, T cells, and fibroblasts in response to inflammatory stimuli. This cytokine regulates acute-phase protein synthesis in the liver, promotes B cell differentiation into antibody-producing plasma cells, and influences T cell activation. IL-6 also contributes to fever induction and has important functions in both innate and adaptive immunity, making it a valuable biomarker for inflammatory conditions and immune system research.

The Sheep Interleukin 6 ELISA Kit (CSB-E10116Sh) is designed for quantitative measurement of IL-6 in Ovis aries samples. This competitive assay can detect IL-6 concentrations ranging from 2 pg/mL to 80 pg/mL with a sensitivity of 2 pg/mL. The kit works with serum, plasma, and tissue homogenates, requiring 50-100 μL sample volume per well. Results are obtained through spectrophotometric detection at 450 nm wavelength. Assay completion typically takes 1-5 hours.

Target Background

Function
(From Uniprot)
Cytokine with a wide variety of biological functions in immunity, tissue regeneration, and metabolism. Binds to IL6R, then the complex associates to the signaling subunit IL6ST/gp130 to trigger the intracellular IL6-signaling pathway. The interaction with the membrane-bound IL6R and IL6ST stimulates 'classic signaling', whereas the binding of IL6 and soluble IL6R to IL6ST stimulates 'trans-signaling'. Alternatively, 'cluster signaling' occurs when membrane-bound IL6:IL6R complexes on transmitter cells activate IL6ST receptors on neighboring receiver cells.; IL6 is a potent inducer of the acute phase response. Rapid production of IL6 contributes to host defense during infection and tissue injury, but excessive IL6 synthesis is involved in disease pathology. In the innate immune response, is synthesized by myeloid cells, such as macrophages and dendritic cells, upon recognition of pathogens through toll-like receptors (TLRs) at the site of infection or tissue injury. In the adaptive immune response, is required for the differentiation of B cells into immunoglobulin-secreting cells. Plays a major role in the differentiation of CD4(+) T cell subsets. Essential factor for the development of T follicular helper (Tfh) cells that are required for the induction of germinal-center formation. Required to drive naive CD4(+) T cells to the Th17 lineage. Also required for proliferation of myeloma cells and the survival of plasmablast cells.; Acts as an essential factor in bone homeostasis and on vessels directly or indirectly by induction of VEGF, resulting in increased angiogenesis activity and vascular permeability. Induces, through 'trans-signaling' and synergistically with IL1B and TNF, the production of VEGF. Involved in metabolic controls, is discharged into the bloodstream after muscle contraction increasing lipolysis and improving insulin resistance. 'Trans-signaling' in central nervous system also regulates energy and glucose homeostasis. Mediates, through GLP-1, crosstalk between insulin-sensitive tissues, intestinal L cells and pancreatic islets to adapt to changes in insulin demand. Also acts as a myokine. Plays a protective role during liver injury, being required for maintenance of tissue regeneration. Also has a pivotal role in iron metabolism by regulating HAMP/hepcidin expression upon inflammation or bacterial infection. Through activation of IL6ST-YAP-NOTCH pathway, induces inflammation-induced epithelial regeneration.
