WitrynaThe current paper presents an LC–MS/MS-based approach for quantification of NSE in serum at both reference levels and elevated levels. The analytical approach utilizes selective sample preparation by immunoextraction of all forms of NSE (αγ, γγ, and γ) followed by tryptic digestion, and separation and detection by LC–SRM-MS. ... WitrynaTherefore, LC–MS has been the analytical choice for the separation and identification of analytes in many applications, being food analysis one of the most frequent uses of the LC–MS combination (Di Stefano et al., 2012; Hird et al., 2014; Malik et al., 2010). From the point of view of chemical composition, foods are a heterogeneous matrix ...
