IL-7 ELISA Kit (Interleukin-7)


Human IL-7 ELISA kit is a procedure of detecting in vitro quantitative amounts of interleukin-7 (IL-7) present in human serum, tissue homogenates, other biological fluids and plasma. This assay has a minimum detection limit of 4.688 pg/ml.


Interleukin-7 (IL-7) is a 17.4 kDa protein that consists of six exons, it is also produced by various cells including; endothelial cells, dendritic cells, keratinocytes, hepatocytes and neurons. It can affect survival and proliferation of mature T cells, enhances proliferation and survival of T cell precursors (human and mice) and B cell precursors (mice only), potent enhancer of T cell function and IFN-γ production.

IL-7 is a critical cytokine for both normal T and B lymphopoiesis, a mobilizer of pluripotent stem cells and myeloid progenitors. Possessing vital roles in enhancing T cell function and also able to induces cytokine expression in monocytes. Preclinical studies have indicated that it is capable of accelerating murine lymphocyte regeneration following chemotherapy or bone marrow transplantation treatment, inducing anti-tumor effects (mice only) and useful in expanding anti-HIV-specific human T cells.


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.

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

L. Johnston
PhD Student / University of Glasgow

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.

Dr. P. Anderson
Lecturer / University College London (UCL)

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.
