Interleukin-17 (IL-17) ELISA Kit


Interleukin-17 ELISA kit is designed for analysing in vitro quantitative levels of interleukin-17 (IL-17) in human plasma (EDTA, heparin), serum and cell culture supernatant samples. This assay has a minimum detection limit of < 1.0 pg/ml.


Interleukin-17 (IL-17 or IL-17A) is a secreted glycoprotein that has a molecular mass of 35 kDa, it is a 155 amino acid protein that is disulphide-linked. The structure of IL-17 is made up of a signal peptide (approx. 23 amino acids) that is followed by a 123 amino acid chain region which is characteristic of the typical IL-17 family. Interleukin-17 is a pro-inflammatory cytokine which is produced by T-helper cells and is known to be induced by IL-23. In order for it to carry out its function IL-17 needs to bind to a type I cell surface receptor called IL-17R (can be either IL17RA, IL17RB or IL17RC). In addition to IL-17A, other members of the IL-17 family include IL-17B, IL-17C, IL-17D, IL-17E (also called IL-25) and IL-17F. All members of the IL-17 family display a very similar protein structure, consisting of four highly conserved cysteine residues that are essential for their 3-dimensional shape. These cytokines are also known to be well conserved in mammals, with approx. 62–88% of amino acid conservation between the human and mouse homologs.

The following interleukin-17 ELISA kit is an ideal tool for analysing various types of diagnostic applications.  IL-17 is most notably known for inducing and mediating pro-inflammatory responses, it has also been commonly associated with allergic responses. It has the ability to induce cytokines (IL-1β, IL-6, G-CSF, GM-CSF, TNF-α, TGF-β), chemokines (IL-8, MCP-1 and GRO-α) and prostaglandins (PGE). Interleukin-17 can also acts with IL-22 in order to induce expression of antimicrobial peptide by keratinocytes. Recent studies have indicated that the IL-23/IL-17 pathway could play a major role in the autoimmune disorder psoriasis. In this condition, immune cells are known to react to inflammatory molecules which have been released within the skin around the joints and scalp. Due to its involvement in immune regulatory functions, there are many IL-17 inhibitors which are being investigated for potential treatments for autoimmune diseases (such as psoriasis, inflammatory bowel disease and rheumatoid arthritis). This interleukin-17 ELISA kit offers a sensitivity level of 1.0 pg/ml and it can be used to measure human samples of plasma, cell culture supernatant and serum.


The minimum detection sensitivity level of IL-17 (interleukin-17) using current human interleukin-17 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.
