However, evaporated water in the outlet tube assembly must be eliminated by discarding 15-20 mL before dispensing into appropriate daily use laboratory standard bottles (30-100 mL). Glass bottles for daily aliquots showed good integrity properties, but only if their fill level was >50%. The use of a low-cost pressurized metal beverage keg dispensing systems provides a robust solution to enable laboratories to maintain the integrity of their water isotope working reference materials over several years. The use of a low-cost pressurized metal beverage keg dispensing systems provides a robust solution to enable laboratories to maintain the integrity of their water isotope working reference materials over several years. Inflammation is a cascade of events mediated by a cytokine network triggering the cellular response. In order to monitor the modulation of the crucial inflammatory proteins, e.g., Tumour Necrosis Factor-α (TNF-α), Interferon-γ (INF-γ), Interleukin-8 (IL-8) and Interleukin-10 (IL-10), upon stimulation with endotoxins, differentiated and undifferentiated THP-1 cells were treated with lipopolysaccharides (LPSs) from E. coli, a key cell wall component of Gram-negative bacteria. The MRM/MS method was optimized by using the standard proteins to be quantified, in order to build up the external calibration curves and define the analytical parameters. The developed method was used to quantify the mentioned above inflammatory proteins in THP-1 differentiated cells upon stimulation with LPSs with high accuracy, sensitivity, and robustness. The analysis of such proteins by MRM mode allowed to follow the kinetic of stimulation along the
