  • Angiotensin II in rat brain comigrates with authentic angiotensin II in high pressure liquid chromatography. (ahajournals.org)
  • To answer directly the question of whether angiotensin II exists in the brain, independent of blood-borne angiotensin, and to quantify the amounts in different parts of the central nervous system, a sensitive radioimmunoassay was used to measure extracts of male adult rat brain hypothalamus and cortex after purification with high pressure liquid chromatography with a high recovery.

  • SepPak C-18 purification preceded reverse phase high pressure liquid chromatography. (ahajournals.org)
  • High pressure liquid chromatography revealed two peaks, one which comigrated precisely with [Ileangiotensin II, and another smaller peak which overlapped with [Ileangiotensin III. (ahajournals.org)

  • The efficacy of a newly developed gas chromatography-negative ion chemical ionization-mass spectrometry-selected ion monitoring (GC-NICI-MS-SIM) assay for measuring globin adducts of benzo[a]pyrene (B[a]P) and chrysene diol epoxides in human was evaluated. (aacrjournals.org)
