Thatcher Abstract The renin-angiotensin-aldosterone system (RAAS) is a complex system of enzymes, receptors, and pep- tides that help to control blood pressure and fluid homeostasis. Techniques in studying the RAAS can be difficult due to such factors as peptide/enzyme stability and receptor localization. This paper gives a brief account of the different components of the RAAS and current methods in measuring each component. There is also a discussion of different methods in measuring stem and immune cells by flow cytometry, hypertension, atherosclerosis, oxidative stress, energy balance, and other RAAS-activated phenotypes. While studies on the RAAS have been performed for over 100 years, new techniques have allowed scien- tists to come up with new insights into this system. These techniques are detailed in this Methods in Molecular Biology Series and give students new to studying the RAAS the proper controls and technical details needed to perform each procedure. Key words Angiotensin, Historical, RAAS, Techniques, Methods 1 Introduction The renin-angiotensin-aldosterone system (RAAS) is an important endocrine system responsible for the control of blood pressure, sodium levels, and extracellular fluid homeostasis. Since the discov- ery of renin, by Tiegerstedt and Bergman in 1898, a tremendous amount of work has been published in understanding the RAAS and the involvement of this system in pathophysiology. There are numerous reviews on the RAAS, and this review will focus on com- ponents of the system and assays that are now typically used in the study of the RAAS. 1.1 Renin Renin was the first component to be measured by Tiegerstedt and Bergman when they injected kidney extracts into rabbits and noticed that this induced hypertension in their model [1]. Since this time, work on purification of renin (40 kilo-dalton (kDa)) and understand- ing the role of renin activity in plasma of different animal models has Sean E.
