CCL22 ELISA kit is intended for detecting in vitro quantitative levels of CCL22 (MDC, macrophage-derived chemokine) in human tissue homogenates, plasma, serum and biological fluids. This assay has a minimum detection limit of 37.5 pg/ml.


Chemokine, cc motif, ligand 22 (CCL22) which can also be known as macrophage-derived chemokine (MDC) and small inducible cytokine subfamily A, member 22 (SCY22), is not particularly related to other chemokines. It only displays approx. 37% amino acid similarity with the thymus- and activation-regulated chemokine (TARC). The CCL22 gene is one of many different Cys-Cys (CC) cytokine genes clustered that are located on the q arm of chromosome 16. They display chemotactic activity for dendritic cells, chronically activated T lymphocytes, monocytes and natural killer cells.

CCL22 is a unique member of the CC chemokine family that has a fundamental role in the function of monocytes, dendritic cells and natural killer cells. The protein can elicits its effects on its target cells by interacting with cell surface chemokine receptors for example CCR4. The gene itself is located in the human chromosome 16 in a cluster along with other chemokines known as CCL17 and CX3CL1.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

The minimum detection sensitivity level of MDC (macrophage-derived chemokine, CCL22) using current CCL22 ELISA kit was approximately 37.5 pg/ml. The dynamic range for this assay is 62.5 – 4,000 pg/ml.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

L. Johnston
PhD Student / University of Glasgow

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
