| Study ID | ST002096 |
| Study Title | Addressing batch effects in large-scale metabolomics with augmented experimental design and meta-analysis (Part 2) |
| Study Summary | Non-polar and polar sequential extracts were collected on three groups of C. elegans: natural isolates, central metabolism mutants, and UDP-glucuronosyltrasnferase mutants. Untargeted LC-MS (HILIC/RP - positive and negative mode) and NMR (CDCl3/H2O) studies were conducted using a Vanquish UHPLC coupled to an Orbitrap Elite MS and NEO 800 MHz Bruker NMR spectrometer, respectively. An augmented design, rank transformation of the raw data, strict feature filtering and QA/QC followed by a meta-analysis was performed on all datasets to demonstrate the benefits of this analysis approach and identify stable, significant features to prioritize for downstream compound identification efforts. |

| Collection ID: | CO002173 |
| Collection Summary: | Escherichia coli (E. coli) IBAT (iterative batch average method) reference material and food source used throughout this experiment. Briefly, for each biological sample, a large-scale culture plate (LSCP) was used to generate a large mixed-stage population of worms (four to seven LSCP replicates per test strain). For each LSCP, worms were collected, population size estimated, and subsequently divided into at least 12 identical aliquots of 200,000 worms in ddH2O and flash-frozen in liquid nitrogen and stored at -80°C. As a quality control sample, C. elegans IBAT reference material was generated and saved in 200,000 worm aliquots. |
