Interleukin-16 (IL-16) ELISA Kit

  • Created on the 12 March, 2017.


Interleukin-16 (IL-16) which was also previously known as lymphocyte chemoattractant factor (LCF), is essentially a lymphocyte chemo-attractant factor of T cell origin that as a selective activity for CD4+ T cells. IL-16 is a product of eosinophils, CD4+ cells, CD8+ cells, epithelial cells derived from asthmatics and mast cells. The expression of IL-16 in asthmatic epithelium is found to directly correlate with the number of infiltrating CD4+ T cells. In addition to its chemotactic activity, it is also a competence growth factor that is selective for CD4+ T cells that are dependent on an interaction with CD4 in order to induce their of functional activity.

Interleukin-16 cDNA is known to code for a novel 14-kDa protein, which needs to form a homo-tetrameric complex in order to induce biological activity. In culture supernatants IL-16 appears as a relative molecular mass (Mr) of approx. 56,000 biologically active, non-covalently linked tetramer, but is found to migrate in monomeric form in SDS PAGE. The eluted monomeric peptides are inactive but have the ability to re-aggregate to Mr 56,000 which allows them to regain biological activity. The protein that is expressed from the IL-16 cDNA is able to demonstrate all the functions and chemical features of the native protein.


Interleukin-16 ELISA kit is a procedure for detecting in vitro quantitative amounts of interleukin-16 (IL-16) in human plasma, serum, cell culture supernatant and other biological fluids. This assay has a minimum detection limit of < 20.0 pg/ml.


The minimum detection sensitivity level of interleukin-16 (IL-16) using this human interleukin-16 ELISA kit was approximately 20.0 pg/ml. The dynamic assay range for this kit is 20.0 – 3,200 pg/ml.

Your secretory IgA ELISA kit 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 kit performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA kits 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 kits. You have such an easy and simple system, yet it is very effective.
