HTRF Human IL-31 Detection Kit, 500 Assay Points
The HTRF human IL31 kit is designed for the quantification of human IL31 release in cell supernatant.
For research use only. Not for use in diagnostic procedures. All products to be used in accordance with applicable laws and regulations including without limitation, consumption & disposal requirements under European REACH regulations (EC 1907/2006).

Product information
Overview
IL31 is preferentially produced by TH2 cells, and acts on activated monocytes and unstimulated epilial 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 detection of low levels of analytes in serum or plasma. When assaying, always follow recommended protocol and avoid highly haemolyzed samples.

How it works
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 Revvity 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.
To fully understand how to deal with HTRF data processing and also 4PL 1/y² fitting,
Revvity also worked with Myassays.com to help you in your data analysis. you’ll be able to access a free online software to run your IL31 analysis.

Analytical performance
Intra and inter assay
Intra-assay (n=24)
| Sample | Mean [IL31] (pg/mL) | CV |
|---|---|---|
| 1 | 199 | 7% |
| 2 | 9888 | 6% |
| 3 | 20883 | 5% |
| Mean CV | 6% |
Each of the 3 samples was measured 24 times, and % CV was calculated for each sample.
Inter-assay (n=4)

| 2 | 1878 | 1674 | 11% |
| 3 | 9091 | 4007 | 4% |
| Mean CV | 11% |
Each of the samples was measured in 4 different experiments, and % CV was calculated for each sample.
