Proteomic studies of plasma membrane proteins are challenged by the limited solubility of these proteins and the limited activity of proteolytic enzymes in solubilizing agents such as SDS. In this work, we have evaluated three bottom-up workflows to obtain tryptic peptides from plasma membrane proteins solubilized with 2% SDS. The workflows are in-gel digestion, in-solution digestion, and on-filter digestion. The efficiencies of these strategies, optimized to employ different matrices for trypsin cleavage, were compared using a plasma membrane sample enriched from multiple myeloma cells using a nanoparticle pellicle. On the basis of the number of proteins identified, number of transmembrane proteins identified, hydrophobicity, and spectral count per protein, the workflow that uses in-gel digestion is the most advantageous approach for analysis of plasma membrane proteins.
