Rat Angiotensinogen ELISA Kit (AGT)

Full Name: Rat Angiotensinogen ELISA Kit (AGT)
Reactivity: Rat
Sample Type: Serum, Urine, Plasma, Cell Culture Supernatant
Sensitivity: 0.02 ng/ml


Angiotensinogen (AGT) is an important member of the serpin family of proteins, it is an alpha-2-globulin that is constitutively produced and released into circulation by the liver. Predominant function involves regulating fluid balance and blood pressure through the renin-angiotensin system. The concentration of plasma angiotensinogen can be elevated by increasing plasma estrogen, corticosteroid, angiontensin II and thyroid hormone levels. It is catalytically cleaved by renin to generate angiotensin I under conditions of low blood pressure.

Pregnant women create the most angiotensinogen, which is mostly made in the liver and the adrenal glands. The renin-angiotensin-aldosterone system (RAAS) causes an increase in blood pressure. through increasing cardiac output and constricting blood vessels. Then, AGT is created and released into the bloodstream, where it aids in boosting angiotensin II secretion and aldosterone activity. The primary regulatory organs are the kidneys, which release renin when certain stimuli increase pressure (like exercise) and lower blood pressure. The primary regulatory organs are the kidneys, which release renin when certain stimuli increase pressure (like exercise) and lower blood pressure. Vasopressin and aldosterone are both made by Ang II. When Ang I attaches to G-protein-coupled receptors on cells, the kidneys change it into Ang III (Ang III), a secondary mediator that raises blood pressure.


Rat angiotensinogen ELISA kit can be used for measuring quantitative levels of AGT (angiotensinogen) in rat plasma, serum, cell culture supernatant and urine samples. This assay has a minimum sensitivity detection limit of 0.02 ng/ml.


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.

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.
