Interleukin-2 (IL-2) ELISA Kit


Interleukin-2 ELISA kit is a method for determining in vitro quantitative amounts of interleukin-2 (IL-2) in human serum, cell culture supernatant, plasma (heparin, citrate, EDTA). This assay has a minimum detection limit of < 0.1 pg/ml.


Interleukin-2 (IL-2) which was also originally known as T-cell growth factor, is produced by antigen- or lectin-activated T cells and is a powerfully immune-regulatory lymphokine. It is not only formed by the stimulation of mature T lymphocytes but also constitutively by a number of T-cell lymphoma cell lines. It has vital functions in the regulation of activation and proliferation of lymphocytes which have already been primed by antigens. Interleukin-2 also has a central role in the expansion of B-cells, T-cells and natural killer cells during certain phases of their response.

The following interleukin-2 ELISA kit is ideal for analysing many different diagnostic applications. The human gene for interleukin 2 (IL-2) is located on chromosome 4. Human IL-2 is made up of 153 amino acids in the precursor form or 133 amino acids in the mature form and it is a 15.5KDa glycoprotein. Due to its central role in the immune response process, IL-2 has become a very important for many therapeutic and diagnostic implications. There is evidence to suggest that it may also display anti-tumoral effects which can be particularly useful in cancer therapy. By monitoring the levels of interleukin 2 in serum this can provide a better insight into several pathological situations such as rheumatoid arthritis, transplant rejection, cancer, multiple sclerosis, type I diabetes, systemic lupus erythematosus and infectious diseases. However, this issue with IL-2 toxicity is still a major concern and merit investigation. This interleukin-2 ELISA kit offers a sensitivity level of 0.1 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-2 (interleukin-2) using current human interleukin-2 ELISA kit was approximately 0.1 pg/ml. The dynamic range for this assay is 15.6 – 1,000 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.
