Human CCL4 (MIP1beta) Assay Kit

Also known as MIP-1beta (macrophage inflammatory protein 1 beta), CCL4 is a chemokine secreted by activated leukocytes, lymphocytes, endothelial and muscle cells in response to microbial infection but also ischemia or asthma.
Cisbio's Human CCL4 kit is a homogeneous, add and read assay to measure CCL4 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.
