Method for measuring the amount of angiotensin peptide in sample and assay kit for angiotensin sin peptide

摘要

Problem to be solved: to provide a method for measuring an amount of an angiotensin peptide in a sample capable of accurately quantifying an angiotensin peptide and an assay kit for an angiotensin peptide.A method for measuring the amount of an angiotensin peptide in a sample, after mixing an isotopically labeled anisotensin peptide to the sample, refining the endogenous angiotensin peptide and the isotopically labeled angiotensin peptide from the sample A method for detecting and quantifying the purified endogenous angiotensin peptide and the isotopically labeled anandensin peptide with mass spectrometry is provided inThe limit of quantification of nintentensin peptide is 0.1 fmol / μ L or less. An assay kit for an angiotensin peptide comprises an isotopically labeled anorthotensin peptide and a denaturant.No selection
