Extraction 3 solvent system MeOH – CHCl 3 – dH 2 O (-20 °C) WORK ON ICE Sample Handling and Extraction for NMR-Based Metabolomics: Protocols for tissue, body fluids and cell extraction, protocols and equipment for sample lyophilization and complete sample workup for NMR data acquisition. A gas chromatography mass spectrometry (GC-MS) metabolomics protocol was modified for quenching, harvesting, and extraction of metabolites from adherent cells grown under high (20%) fetal calf serum conditions. This is time-consuming and difficult to automate, and the multiple steps can introduce variability. The best starting material for tissue metabolomics are small pieces of tissue snap-frozen in liquid nitrogen to quench the metabolism. These approaches to assess protocol suitability proved to be inadequate to judge earthworm tissue extraction methods because of sample instability. The described extraction protocol provides a simple and straightforward method for the efficient extraction of lipids, metabolites and proteins from minute amounts of a single sample, enabling the targeted but also untargeted high-throughput analyses of diverse biological tissues and samples.
