Urine fibronectin co-purified proteins identified by mass spectrometry.

Multiple co-purified proteins of fibronectin could be identified in urine of FIC cases by LC-MS/MS of which eight are listed. a) Accession number as listed on Uniprot (http://www.uniprot.org) or Ensembl (http://www.ensembl.org) databases, b) Number of peptides the protein was identified with, c) Confidence score as given in Mascot were considered as significant if the value was higher than 30 (*p≤0.01), d) Ratio of control IP and FIC IP cumulated peptide intensity signal strengths (progenesis values).
