We combined glycopeptide enrichment by N-glyco-FASP (Zielinska et al., 2010), SPEG (Tian et al., 2007) with a hydrophobic segment-oriented hpTC method (Vít et al 2016) and a standard “detergent and trypsin” approach into a tree-pronged “Pitchfork” strategy for the analysis of membrane proteome in high-risk human paraganglioma.
