Human IL31 kit HTRF®
The HTRF human IL31 kit is designed for the quantification of human IL31 release in cell supernatant.
-
No-wash
-
Low sample consumption
-
Under 2h bench time
Overview
IL31 is preferentially produced by TH2 cells, and acts on activated monocytes and unstimulated epithelial cells. It could be involved in skin inflammation, in particular pruritus (itching).
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-31 alpha 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.
Benefits
- SCALABLE FROM 96 TO 1536WELLS
- TH2 CELLS ACTIVATION READOUT
Assay principle
Assay data analysis
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.
