Interleukin-10 (IL-10) ELISA Kit


Human IL-10 ELISA kit can be used for determining in vitro quantitative amounts of interleukin-10 (IL-10, interleukin 10) in human serum, biological fluids, plasma and many other biological fluids. This assay has a minimum detection limit of 4.688 pg/ml.


Interleukin-10 (IL-10) is a member of the four a-helix bundle family with a molecular mass of 39 kDa (160 amino acids) and in solution human IL-10 is only functional has a homodimer. It is essentially a pleiotropic cytokine which plays important roles in regulating lymphoid and myeloid cell functions. IL-10 is a potent suppressor of the effector functions of T-cells, macrophages and NK cells since it has the ability to block the synthesis of cytokines and several accessory cell functions of macrophages. Interleukin-10 is found to be expressed by a number of different cells which includes B cells derived from peripheral blood, EBV-transformed B cell lines, Burkitt’s lymphoma, placental trophoblasts, monocytes, bronchial epithelial cells, AIDS lymphomas, certain melanomas and carcinomas.

Human IL-10 gene is found to be located on chromosome 1 and it is often occurring as a single copy within the genome. It displays strong amino acid sequence and DNA sequence homology to the murine IL-10, it also exhibits similarity to the open reading frame present in the Epstein Barr virus genome and BCRF1. This led to implications there is a possibility that IL-10 may also play a role in the host-virus interactions.

The immunosuppressive properties that are shown by IL-10 indicate a potential clinical use for IL-10 in suppressing rejections of grafts following organ transplantations. There is a further possibility of it exerting a strong anti-inflammatory activities too. In many diseases for example Leishmania, Schistosoma mansoni, Trypanosoma and Toxoplasma gondii infections the levels of interleukin-10 have been found to be elevated. High concentrations of IL-10 are also found in mycobacterial infections (Mycobacterium leprae, Mycobacterium avium and Mycobacterium tuberculosis) and in retroviral infections inducing immunodeficiency.

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.

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.
