Mass Spectrometry-based Proteomics in Microvascular Inflammation Diagnosis in Kidney Transplantation.

"The biopsy and urine samples will be processed by the OncoProt platform (University of Bordeaux) for proteomic analysis by tandem mass spectrometry (label-free quantification) as follows:~* Biopsies: laser microdissection of the renal cortex, fixation reversion, protein extraction and electrophoretic migration, tryptic digestion.~* Urines: samples concentration by centrifugation/filtration and tryptic digestion according to a protocol adapted from the FASP method (Filter-Aided Sample Preparation)"
