Interleukin-9 (IL-9) ELISA Kit


Interleukin-9 ELISA kit is designed for detecting in vitro quantitative concentrations of interleukin-9 (IL-9) present in human serum, plasma, cell culture supernatant and many other biological fluids. This assay has a minimum detection limit of < 0.343 pg/ml.


Interleukin-9 (IL-9) is a pro-inflammatory cytokine which was originally identified as a 40KD glycoprotein with T-cell growth factor activity in mice. The human IL-9 was later discovered on the basis of its high level of homogeneity with the gene of mouse IL-9. Human IL-9 has be strongly associated with human malignant lymphoma and also demonstrated to be a stimulator for hematopoiesis. Furthermore, its expression has been found to be implicated with autoimmune and many allergic diseases.

The following interleukin-9 ELISA kit is ideal for analysing many different diagnostic applications. IL-9 is well studied as a therapeutic target for asthma due to it being implication with the disease.  IL-9 can be produced by Th2 cells which are under the stimulation of TGF-b and IL-4. This lineage has been shown to play vital role in the differentiation of Th17 cells and Treg function. There has been a renewed attention on IL-9 in recent years due to a unique type of innate lymphoid cells which have been discovered in mice where the main cell types expressing IL-9 secreting and in vivo cells present with the skin appear to mediate the inhibition of melanoma growth. These same interleukin-9 secreting cells have now also been identified in human and are being evaluated as a new tumour treatment strategy. This interleukin-9 ELISA kit offers a sensitivity level of 0.343 pg/ml and it can be used to measure human samples of cell culture supernatant, biological fluids, plasma and serum.


The minimum detection sensitivity level of IL-9 using current human interleukin-9 ELISA kit was approximately 0.343 pg/ml. The dynamic range for this assay is 0.78 – 50 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.
