    SCIEX quadrupole time of flight tripletof 5600 mass spectrometer
    Workflow for ErbB2 targeted proteomics using multiprotease digestion and high resolution mass spectrometry quantitation. ErbB2 immunopurified from four 15 cm plates of untreated SK-BR-3 cells was pooled into a single sample. The sample was split into 12 aliquots and separated by SDS-PAGE. Triplicate in-gel digestion was performed using either trypsin, Asp-N, chymotrypsin, or a double digestion with trypsin plus Asp-N. Each sample was analyzed using an AB SCIEX <t>TripleTOF</t> 5600 mass spectrometer. Two approaches for high resolution LC-MS/MS quantitation were employed, MS1 Filtering and SWATH MS2 acquisition.
