    Why phosphoproteomics is still a challenge
    (Cambridge : Royal Society of Chemistry, 2015) Solari, Fiorella A.; Dell'Aica, Margherita; Sickmann, Albert; Zahedi, René P.
    Despite continuous improvements phosphoproteomics still faces challenges that are often neglected, e.g. partially poor recovery of phosphopeptide enrichment, assessment of phosphorylation stoichiometry, label-free quantification, poor behavior during chromatography, and general limitations of peptide-centric proteomics. Here we critically discuss current limitations that need consideration in both qualitative and quantitative studies.
