CCL17 ELISA kit is procedure for measuring in vitro quantitative concentrations of CCL17 (TARC) in human serum, cell culture supernatant and plasma (EDTA, heparin). This assay has a minimum detection limit of < 1.0 pg/ml.


Chemokine (C-C motif) ligand 17 (CCL17) which is also commonly known as thymus and activation regulated chemokine (TARC), is a cytokine which is part of the CC chemokine family. The gene can be found located on chromosome 16, along with two other chemokines known as CX3CL and CCL22. The chemokine has the ability to bind and induce specific chemotaxis activity within T cells and it carries this function out by interacting with the CCR4 receptor.

This CCL17 ELISA kit is designed for analysing many different types of diagnostic applications. CCL17 (TARC) is found to be produced in lymph node dendritic cells, thymic dendritic cells, CD4+ T cells, monocytes, Reed-Sternberg cells, bronchial epithelial cells, fibroblasts and keratinocytes. It is expressed constitutively in thymus, but only transiently in peripheral blood mononuclear cells that have been phyto-hemagglutinin stimulated. One of the main function of CCL17 is the promotion of Th2 cell recruitment to sites of inflammation and in inducing platelet degranulation and aggregation. The standard used in the following CCL17 ELISA kit is recombinant human CCL17 which is made up of 71 amino acids and has a molecular weight of 8Kda.


The minimum detection sensitivity level of TARC (CCL17) using current human CCL17 ELISA kit was approximately 1.0 pg/ml. The dynamic range for this assay is 31.2 – 2,000 pg/ml.

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

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.

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.

You are my first point of contact when I am looking to purchase ELISA. You have such an easy and simple system, yet it is very effective.
