Human CCL20 Assay Kit

Also called LARC (liver activation-regulated chemokine) or MIP3A (macrophage inflammatory protein 3), CCL20 is a chemokine mainly present in peripheral blood lymphocytes, lymph nodes and liver. CCL20 secretion is upregulated by microbial factors and inflammatory cytokines like TNFa or IFNg. Its main role is to attract lymphocytes and dendritic cells to the site of infection.
In CNS, CCL20 released by endothelial cells has been shown to attract TH17 cells and promote their infiltration to the lumbar spinal cord.
Cisbio's Human CCL20 kit is a homogeneous, add and read assay to measure CCL20 secretion in supernatant. It offers a fast, efficient alternative to ELISA.

Assay principle

The assay protocol, using a Cisbio 96-well low volume or a 384-well small volume white plate (20 µL final), is described below. Cell supernatant, sample or standard are dispensed directly into the assay plate for the detection by HTRF® reagents. 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 in 96 to 1536-well plates by simply resizing each addition volume proportionally.

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.
