Endothelin-3 ELISA Kit


Human endothelin-3 ELISA kit is a reliable quantitative procedure for measuring ET-3 (endothelin-3, EDN3) in human tissue extracts, cell culture media, serum and plasma (EDTA). This assay has a minimum sensitivity detection limit of 0.36 pg/ml.


Endothelin-3 (ET-3, EDN3) is a member of the endothelin family of proteins and in humans is encoded by the EDN3 gene. These are essentially endothelium-derived vasoactive peptides which are involved in a number of different biological functions. The active form of this protein is a 21 amino acid sequence that is formed by the cleavage of the precursor protein. This is a ligand for endothelin receptor type B (EDNRB) and the interaction of this ligand with human endothelin-3 is essential for development of many neural crest-derived cell lineages for example enteric neurons and melanocytes. Any mutations in this gene and EDNRB are known to be linked to Waardenburg syndrome (WS) and Hirschsprung disease (HSCR), both of which are neural crest-derived cell congenital disorders. The levels of endothelin-3 are found to be elevated in colon carcinoma, this is responsible for supporting cell survival and proliferation.


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.

  • Precoated Microplate: Wells bound with ET-3 antigen 15-21 rabbit IgG affinity purify.

The minimum sensitivity detection limit of endothelin-3 (EDN3) using current human ET-3 ELISA kit was approximately 0.36 pg/ml. The dynamic range for this assay is 0.78 – 100.0 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.
