Interleukin 6 (IL-6) which can also be called by many other names including interferon-beta 2 gene (IFNB2), hybridoma growth factor (HGF) and hepatocyte stimulating factor (HSF) and B-cell stimulation factor-2 (BSF-2). IL-6 is a multi-functional protein that important functions in immune responses, host defence, hematopoiesis and acute phase reactions. The proteins which are derived from this gene are known to be responsible for mediating the plasma protein response to tissue injury (called the acute-phase response) and regulating the growth and differentiation of both T and B cells. It is not only involved in the hepatic acute phase response but is also responsible for lipoprotein lipase activity, hepatic triglyceride secretion and adipose tissue metabolism. The overproduction of interleukin 6 has been associated with a large spectrum of age-related conditions such as osteoporosis, arthritis, cardiovascular disease, certain cancers, type 2 diabetes, periodontal disease, functional decline and frailty.
IL-6 is predicted to contain a four helix-bundle type tertiary structure that is common among other cytokines such as G-CSF, IL-11, MGF, OSM, CNTF, EPO, LIF, hGH and prolactin. The results of structure-function studies of IL-6 and the other four a-helix bundle cytokines indicates that the helix D regions (c-terminal) are mainly responsible for the binding to their respective receptors. IL-6 is expressed by a number of different normal and transformed cells which can include vascular endothelial cells, monocytes/macrophages, T cells, B cells, astrocytes, osteoblasts, hepatocytes, mesangial cells, keratinocytes, fibroblasts, melanomas, glioblastomas, myelomas, carcinomas and sarcomas. Also, the production of interleukin-6 can be up-regulated by many signals such as antigenic or mitogenic stimulation, calcium ionophore, lipopolysaccharide, IL-1, IL-2, PDGF, TNF, IFN and viruses. Whereas, both IL-4 and IL-13 are known to inhibit IL-6 expression within monocytes. The many different activities of IL-6 suggest that this factor plays a vital role in the mediating the immune and inflammatory responses.
Interleukin-6 ELISA kit is intended for measuring in vitro quantitative concentrations of interleukin-6 (IL-6) present in human serum, cell culture supernatant and plasma (EDTA, citrate, heparin). This assay has a minimum detection limit of < 0.3 pg/ml.
The minimum detection sensitivity level of interleukin-6 (IL-6) using this human interleukin-6 ELISA kit was approximately 0.3 pg/ml. The dynamic assay range for this kit is 4.69 – 300 pg/ml.
