Furin cleavage of bacterial expressed glutathione-S-transferase-pro-transforming growth factor beta1 fusion protein in vitro.

abstract：:Identification and elimination of noise peaks in mass spectra from large proteomics data streams simultaneously improves the accuracy of peptide identification and significantly decreases the size of the data. There are a number of peak filtering strategies that can achieve this goal. Here we present a simple algorith...
