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.

Assay principle

Cell supernatant, sample, or standard is dispensed directly into the assay plate for the detection by HTRF® reagents (384-well low-volume white plate or Cisbio low-volume 96-well plate in 20 µl). The antibodies labeled with the HTRF donor and acceptor are pre-mixed and added in a single dispensing step, to further streamline the assay procedure. The assay can be run up to a 1536-well format by simply resizing each addition volume proportionally.

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.
