Interleukin-3 (IL-3) ELISA Kit


Interleukin-3 ELISA kit is a procedure for analysing in vitro quantitative levels of interleukin-3 (IL-3) in human plasma (heparin, EDTA, citrate), serum and cell culture supernatant samples. This assay has a minimum detection limit of < 0.1 pg/ml.


Interleukin-3 (IL-3) is essentially a hematopoietic colony-stimulating factor (CSF) which has the ability to support the proliferation of a large number of hematopoietic cell types. It is a protein that is 140 amino acids in length which is chemically synthesised using an automated peptide synthesiser and this displays biological activities that can be attributed to native IL-3. The gene IL-3 in known to encode interleukin 3, where the human gene encoding IL-3 is found to be tandemly arrayed on the long arm of chromosome 5.

The mouse IL-3 gene is located on chromosome 11 and the cDNA sequence for codes for a polypeptide of 166 amino acids including a putative signal peptide. It is regarded as one of the colony stimulating factors that is vital in regulating haematopoiesis. The standard used in the following interleukin-3 ELISA kit is a recombinant human IL-3 that is composed of 133 amino acids having a total molecular mass of 15KDa.


The minimum detection sensitivity level of IL-3 (interleukin-3) using current human interleukin-3 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.
