COMPOSITIONS AND METHODS FOR PLASMA PEPTIDE ANALYSIS

摘要

Provided herein are composition, methods and kits for peptide analysis in blood by mass spectroscopy. Isotopic peptides are also provided that facilitate quantification of peptide levels, e.g., hepcidin levels, in blood by mass spectroscopy. Further disclosed are methods and compositions for quantifying blood hepcidin levels and evaluating iron-associated disorders.
