Coupling methanol denaturation, immobilized trypsin digestion, and accurate mass and time tagging for liquid chromatography-based shotgun proteomics of low nanogram amounts of RAW 264.7 cell lysate

We report the shotgun proteomic analysis of mammalian cell lysates that contain low nanogram amounts of protein. Proteins were denatured using methanol, digested using immobilized trypsin, and analyzed by UPLC-ESI-MS/MS. The approach generated more peptides and higher sequence coverage for a mixture...
