Human IFN gamma kit
No-wash kit to quantify released Human IFN gamma
The HTRF human IL4 kit is designed for the quantification of human IL4 release in cell supernatant.
IL4 is expressed by T cells, NK cells, and mast cells, and is an important regulator of humoral and adaptative immunity. It stimulates activated B cells, and induces their differentiation into plasma cells and their class switch to immunoglobulin E, as well as promoting class II MHC expression. In immuno-oncology, IL4 induces the differentiation of naïve T cells into TH2 cells, which in turn produce IL4 and thus create a positive feedback loop. IL4 is also involved in the development of airway inflammation and allergic asthma.
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-4 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.
