Angiotensinogen ELISA Kit (AGT)


Human angiotensinogen ELISA kit is a reliable quantitative method for detecting angiotensinogen (AGT) in human tissue homogenate, serum, plasma and other biological fluids. This assay has a minimum sensitivity detection limit of 0.18 ug/ml.


Angiotensinogen (AGT) is important in regulating blood pressure and fluid balance. It is a component of the renin-angiotensin system (RAS). It is synthesised in the liver and secreted into the plasma, it also appears to be associated with; predisposition to essential hypertension, heterogeneous disorders, pregnancy-induced hypertension (pre-eclampsia), foetal or neonatal mortality and morbidity. In recent studies the interested associated to the role of renin-angiotensin system in arterial pressure control and pathophysiology of hypertension has shifted to its specific role locally in various tissues.

Also, angiotensinogen is can be catalytically cleaved by renin to order to generate angiotensin I under conditions where blood pressure is lowered. Angiotensin converting enzyme (ACE) is then able to subsequently remove a dipeptide leading to the production of angiotensin II, which is the physiologically active peptide and functions in regulating the volume and the mineral balance of body fluids.

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.
