Experimental and analytical workflow. (left): Clinical PD samples (human omental biopsies) of pediatric PD patients and healthy controls; (right): in vitro samples from three different primary HUVEC cultures exposed to diluted conventional PD fluid (PDF) containing or lacking 8 mM alanyl-glutamine (AlaGln), or to control cell culture medium. TMT: tandem mass tags; ESI: electrospray ionization; MALDI: matrix-assisted laser desorption/ionization; IPS: internal pooled standard; 2D RP/RP LC-MS: two-dimensional reversed phase/reversed phase liquid chromatography tandem mass spectrometry; 2D-DiGE: two-dimension difference gel electrophoresis.
