“In biological systems, variable protein expression is a crucial marker for numerous diseases, including cancer. The vast majority of liquid chromatography–triple quadrupole mass spectrometry-based quantitative protein assays use bottom-up methodologies, where proteins are subjected to proteolytic cleavage prior to analysis. …As biological matrices, pooled human urine and pooled human serum were purchased from Innovative Research (Novi, MI, USA)...”
