Table 2 Relative abundance of proteins constituting the matrisome of normal pancreatic islets.

From: Quantitative proteomic profiling of the extracellular matrix of pancreatic islets during the angiogenic switch and insulinoma progression

  1. We defined the matrisome of normal pancreatic islets as the ensemble of 120 ECM and ECM-associated proteins detected in both replicates plus the 58 ECM and ECM-associated proteins detected in one of the two replicate but with at least 2 unique peptides. The relative abundances of ECM and ECM-associated proteins in normal islets were calculated as the precursor-ion-weighted average normalized 117-reporter ion intensity (see Supplementary Table 1D). Proteins are sorted by descending relative abundance (Grey scale represents high abundance in dark shades and low abundance in lighter shades). Asterisk (*) indicates proteins not detected in any of the 14 tissues and tumor types contributing to the previously presented ECM atlas9.
