CCL17 ELISA kit is procedure for measuring in vitro quantitative concentrations of CCL17 (TARC) in human serum, tissue homogenates, plasma and other biological fluids. This assay has a minimum detection limit of 18.75 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.

CCL17 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. It is expressed constitutively in the thymus, but only transiently in peripheral blood mononuclear cells. One of the main function is the promotion of Th2 cell recruitment to sites of inflammation and in inducing platelet degranulation and aggregation.


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.

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.
