Measurement of Renal Tubular Angiotensin II

The proximal tubules play a critical role in providing the kidneys with their ability to regulate body fluid volume and electrolyte composition. One major function is the reabsorption of sodium and other electrolytes which is caused, in part, by angiotensin II (Ang II), a peptide that is made up of eight amino acids. By activating Ang II receptors on both the basolateral and luminal membranes, Ang II serves a major function in determining how the kidney processes
