Study Title | Child Health and Development Studies womb to breast cancer F0 metabolomics |
Study Summary | We used high resolution metabolomics to understand DDT-induced alterations of in utero environment and potential health effects. This study measured endogenous metabolites in 397 maternal perinatal serum samples collected during 1959-1967 in the Child Health and Development Studies (CHDS) and assessed associations between metabolites and envrionmental chemical concentrations in maternal serum. |

MS Comments: | Mass spectral data were collected with a 10-minute gradient on a Thermo QExactive coupled with Dionex Ultimate 3000 (Thermo Fisher, San Diego, CA) set to collect data from m/z 85 to 1275 in positive ionization mode at 70,000 resolution. Three technical replicates were run for each sample using dual chromatography measuring both polarities (positive and negative) with a C18 column (Higgins Analytical, 100x2.1mm, 5uL). The right pump controls the gradient with Solvent A as 100% water, Solvent B as 100% Acetontrile, and Solvent C as 98% water with 2% Formic Acid. The left pump is set up to wash (Acetonitrile with 2% Formic Acid) one of the columns while the other column is running the gradient. The raw data was processed with Xcalibur 3.0.63 |
