Study TitleQuantitative analysis of bile acids in fecal samples from centenarians, elderly and young subjects.
Study SummaryFecal samples from centenarians (>100 yo), elderly (85-89 yo) and young (21-55) subjects were analysed using LC-MS/MS. 48 bile acids were measured by targeted metabolomics.

MS Comments:The following MS parameters were used for the positive ion MRM mode: ion spray voltage; 5,500 V, interface temperature; 500 °C, curtain gas; 30 psi, collision gas (nitrogen); 9 psi, nebulizing gas; 80 psi, and heater gas; 80 psi. For the negative ion MRM mode: ion spray voltage; -4,500 V, interface temperature; 500 °C, curtain gas; 30 psi, collision gas (nitrogen); 9 psi, nebulizing gas; 80 psi, and heater gas; 80 psi. Samples were obtained using Analyst software ver1.71 and analysed using SCIEX OS-MQ software ver1.7.0.36606.
