General description

Angiotensin II (Ang II) is part of the renin-angiotensin cascade. It is an octapeptide. Ang II is present in high concentration in cardiac tissue.

Application

ProteoMass™ Angiotensin II MALDI-MS Standard has been used:
  • as peptide calibration standard for MALDI-MS instruments
  • as a reference standard in Liquid chromatography–mass spectrometry (LC-MS/MS) analysis for characterizing RNase and NC1 domain of collagen IV
  • as a standard in testing infrared (IR) laser desorption/ionization (IR-LDI) method

Biochem/physiol Actions

Angiotensin II (Ang II) maintains cardiac functionality by coordinating with the angiotensin II receptors. Ang II is recommended for patients with vasodilatory shock.

Ultra-Pure MALDI Matrices

One of the most important aspects of our ultra-pure MALDI matrix substances is their ability to dissolve rapidly and completely; a brief vortex mixing is typically sufficient.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
