Mol. Proteomics software tools and databases: Aebersold, R. & Mann, M. Mass-spectrometric exploration of proteome structure and function. On the other hand, the absence of an enrichment step and multiple conditions exacerbates the analytical challenge for low abundance targets and requires significant MS instrument time, in particular for the approaches that rely on robust quantitation of individual peptides and therefore high sequence coverage. Using these principles, it is clear that early SCoPE MS data suffered from quantitative noise and inaccuracies (CV > 40%), but more recent data such as the iBASIL study (above) appears to be much higher quality.
