Angiotensin News and Research

RSS

Angiotensin is an oligopeptide in the blood that causes vasoconstriction, increased blood pressure, and release of aldosterone from the adrenal cortex. It is a powerful dipsogen. It is derived from the precursor molecule angiotensinogen, a serum globulin produced in the liver. It plays an important role in the renin-angiotensin system.

Identifying The Best Antibodies Using X-Rays

Imagine you're going to a party where you only know a single person. While you've been friends with this person for a long time, you're concerned about them leaving you alone in a room full of strangers. Even though they promise they'll stick by your side, they immediately walk away from you upon entering the party to speak to someone else they know.
