Prostaglandin E2 (PGE2) is synthesized within the cortex and medulla of the kidney. It is a signalling molecule produced by activated platelets. It lower the filterability of human erythrocytes by approximately 30% at a concentration of 10-10 M and also caused a reduction in mean cell volume by about 10%. It is naturally produced by the body with both COX1 and COX2 playing important roles. Endogenous PGE2 is made from arachidonic acid which can be found in cell membranes or dietary sources like red meat, eggs, seafood and nuts. Exogenous one is usually made from dietary sources of arachidonic acid, like red meat and eggs. Prostacyclin (I) and PGI2 are both made from arachidonic acid. Prostacyclin is produced in endothelial cells where they produce prostaglandins while platelets, macrophages and mast cells produce PGD2.

Prostaglandin E2 has a significant role in vascular smooth muscle tone regulation. It promotes vasodilation of smooth muscles by increasing the activity of cyclic adenosine monophosphate to decrease intracellular calcium levels via the IP and EP4 receptors. When it interacts with EP3 receptors, it increases body temperature, resulting in fever. It also supports tumor growth by promoting; angiogenesis, stimulating tumor-cell proliferation and protecting tumor cells from apoptosis. It plays multiple roles both in the physiology and the physiopathology of the human brain. An increased expression of PGE-synthase in a subset of human glioblastoma tumors, which catalyzes the isomerization of PGH into PGE2 downstream of COX-2. PGE2 produced by COX-2 may encourage tumour cell motility, angiogenesis, and invasion. Patients who experience recurrent miscarriage have lower levels of trophoblast-derived prostaglandin E2 receptor 2 (EP2) expression. EP2 controls inflammatory cytokine production and cell proliferation. It suppresses hCAP18/LL-37 expression in human macrophages via EP2/EP4: implications for treatment of Mycobacterium tuberculosis infection.


Human prostaglandin E2 ELISA kit can measure levels of PGE2 (prostaglandin E2) present is human plasma, serum, biological fluids and tissue homogenates.

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.

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.
