Human IL4 kit
No-wash kit to quantify released Human IL4
The HTRF human IL12 kit is designed for the quantification of IL12 release in cell supernatant.
Also known as NKSF (natural killer cell stimulatory factor) and CLMF (cytotoxic lymphocyte maturation factor), IL12 is produced by macrophages and B cells. Along with IFN gamma, IL12 promotes the differentiation of naïve T cells into TH1 cells, which in turn release IFNg and IL2. Because of its effects on TH1 induction, IL12 is strongly linked to autoimmunity. IL12 is a heterodimer of p35 and p4,0 which is shared with IL23. Cisbio's IL12 assay is specific for IL12p70 (full form) and does not cross react with IL23.
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-12 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.
