ABOUT THE WORKFLOW This workflow was used to analyze the data in a manuscript by Mostovenko et al. (2012, submitted), comparing proteins in the precipitate with those left in solution after organic solvent precipitation. However, the workflow is generally applicable in comparisons of any binary fractionation method in proteomics, where the fractions are analyzed by liquid chromatography-tandem mass spectrometry. The workflow identifies proteins by SpectraST spectral library search and X!Ta...
