Description

Interleukin-6 is a pleiotropic cytokine central to JAK/STAT3 signaling, acute-phase responses, and B-cell differentiation, making precise functional reagents essential for mechanistic immunology studies. This tag-free recombinant mouse IL-6, encompassing the full mature sequence (25–211 aa), demonstrates exceptional potency with an ED50 below 0.02 ng/mL in 7TD1 proliferation assays, corresponding to a specific activity exceeding 5 × 10⁷ IU/mg — a level that supports use in dose-dependent proliferation assays, STAT3 phosphorylation studies, and NF-κB pathway dissection at minimal working concentrations. Endotoxin levels below 1.0 EU/μg effectively mitigate LPS-driven artifacts in sensitive immune cell cultures, making this protein appropriate for primary B-cell differentiation experiments, in vivo inflammation models, and as a quantitative reference standard in cytokine detection assays. Purity exceeding 97% by SDS-PAGE, combined with this stringent endotoxin profile, satisfies the criteria typical for antibody validation workflows including ELISA coating and functional blocking studies.

Target Background

Function

Cytokine with a wide variety of biological functions in immunity, tissue regeneration, and metabolism (Probable). 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 immunoglolin-secreting cells (Probable). 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. Together with IL21, controls the early generation of Tfh cells and are critical for an effective antibody response to acute viral infection. Required to drive naive CD4(+) T cells to the Th17 lineage, through 'cluster signaling' by dendritic cells. Also required for proliferation of myeloma cells and the survival of plasmablast cells (Probable).; 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 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.
