Extraction efficiency of proteins from different cellular locations. Pie chart showing cellular location of identified proteins after the different protein extraction methods. The percentages were determined using the GO TermMapper, cellular component ontology. Protein identification, at >99%, required at least two unique peptides, at ≥95% confidence level, detected by LC-FTICR MS/MS, searched against the human Swiss-Prot database using MASCOT and X!Tandem
