Zusammenfassung:	An analytical method was developed and validated for the measurement of hydroxyproline (Hyp) levels in mouse kidney by high-performance liquid chromatography with tandem mass spectrometric detection (LC/MS/MS) using an analytical column specially designed for the LC/MS/MS analysis for intact amino acids. Tissue hydrolyzed with hydrochloric acid could be directly injected into the LC/MS/MS, as well as separated and detected using the deuterium labelled Hyp as an internal standard. The calibration curve showed good linearity from 5 to 500 nmol/mg of tissue; the precision and accuracy, including within- and between-run, were less than 6% and within 100 ± 6%, respectively.
