    Isolation and Quantification of Metabolite Levels in Murine Tumor Interstitial Fluid by LC/MS
    Authors:  Mark R Sullivan, Caroline A Lewis and Alexander Muir, date: 11/20/2019, view: 2273, Q&A: 0
    [Abstract] Cancer is a disease characterized by altered metabolism, and there has been renewed interest in understanding the metabolism of tumors. Even though nutrient availability is a critical determinant of tumor metabolism, there has been little systematic study of the nutrients directly available to cancer cells in the tumor microenvironment. Previous ...
    Extraction and Analysis of Pan-metabolome Polar Metabolites by Ultra Performance Liquid Chromatography–Tandem Mass Spectrometry (UPLC-MS/MS)
    Authors:  Dania M. Malik, Seth Rhoades and Aalim Weljie, date: 02/05/2018, view: 4524, Q&A: 0
    [Abstract] Modern triple quadrupole mass spectrometers provide the ability to detect and quantify a large number of metabolites using tandem mass spectrometry (MS/MS). Liquid chromatography (LC) is advantageous, as it does not require derivatization procedures and a large diversity in physiochemical characteristics of analytes can be accommodated through a ...
