Human IL1 alpha kit
No-wash kit to quantify released Human IL1 alpha
The HTRF human IL18 kit is designed for the quantification of human IL18 release in cell supernatant.
Also called IGIF (interferon gamma inducing factor), IL18 is a pro-inflammatory cytokine secreted mainly by macrophages. Its biological activity is close to that of IL12, and it can enhance NK cell activity as well as induce IFNg secretion by PBMC. An important role of IL18 is eliminating VEGF from the eye, thus protecting the retina. It is used together with anti-VEGF antibodies in the treatment of AMD (age-related macular degeneration). In addition to this physiological role, IL18 dysregulation leads to severe inflammatory reactions.
Assessment of serum samples often requires enhanced sensitivity. In some cases, AlphaLISA assays may have sufficient sensitivity to enable the detection of low levels of analytes in serum or plasma. Check out the Human IL-18 AlphaLISA kit’s analytical performances for more information or learn more about AlphaLISA. When assaying, always follow the recommended protocol and avoid highly haemolyzed samples.
The 4 Parameter Logistic (4PL) curve is commonly recommended for fitting an ELISA standard curve. This regression enables the accurate measurement of an unknown sample across a wider range of concentrations than linear analysis, making it ideally suited to the analysis of biological systems like cytokine releases.
