Overview

Also known as hematopoietin 1, IL1 alpha is a pro-inflammatory cytokine mainly produced by activated macrophages, and epithelial and endothelial cells. Its main role is the maintenance and protection of the skin's barrier function. In response to infection, IL1 alpha stimulates fibroblast proliferation, increases blood neutrophils, and activates lymphocyte proliferation.

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.
