Project Title:	Metabolomics analysis of multiple samples
Project Summary:	Liquid chromatography–high resolution mass spectrometry (LC-HRMS) is the most popular platform for untargeted metabolomics methods, but annotating LC-HRMS data is a long-standing bottleneck that we are facing since years ago in metabolomics research. A wide variety of methods have been established to deal with the annotation issue. To date, however, there is a scarcity of efficient, systematic, and easy-to-handle tools that are tailored for metabolomics and exposome community. Herein, we developed a user-friendly and powerful stand-alone software, MetEx, to enable implementation of classical peak detection-based annotation and a brand-new annotation method based on targeted extraction algorithms. Especially the newly proposed annotation method of targeted extraction can identify more than 2 times more metabolites than traditional peak detection-based annotation methods because it reduces the loss of metabolite signal in the data preprocessing process.

Collection:

Collection ID:	CO001943
Collection Summary:	NIST SRM 1950 was purchased from NIST, and HepG2 cells were purchased from the Chinese Tissue Culture Collections (CTCC, Shanghai, China). Urine was collected from volunteers. Six- to eight-week-old male C57BL/6 mice were fed a regular standard breeding diet and housed under standard pathogen-free (SPF) conditions. Faecal samples and liver tissue were collected and immediately stored at -80 °C for further analysis.
Sample Type:	Blood (plasma), Urine, HepG2 cells
Storage Conditions:	-80℃

Treatment:

Treatment ID:	TR001962
Treatment Summary:	No treatment

Sample Preparation:

Sampleprep ID:	SP001956
Sampleprep Summary:	Plasma (NIST SRM 1950): A 240 μL volume of Mix-IS-ACN was added to 60 μL of NIST SRM 1950 for protein precipitation. Then, the sample was vortexed for 60 s and centrifuged for 10 min at 15,000 g and 4 °C. Then, 250 μL of supernatant was transferred to a new centrifuge tube for lyophilization. The residue was reconstituted with 60 μL of 90% H2O/CH3OH (v/v). Urine: A 60 μL sample of urine was centrifuged for 10 min at 15,000 g and 4 °C, and the supernatant was transferred to a new centrifuge tube. Then, 30 μL Mix-IS-MeOH was added to the same centrifuge tube, and the mixture was thoroughly combined on a vortex mixer for 60 s. HepG2: HepG2 cells were purchased from the Chinese Tissue Culture Collections (CTCC, Shanghai, China) and cultured in Dulbecco’s modified Eagle’s medium (DMEM, Gibco) supplemented with 10% fetal bovine serum (FBS, Gibco), 100 IU/ml penicillin and 100 µg/ml streptomycin (Gibco). These cells were cultured at 37 °C in a humidified 5% CO2 atmosphere and treated within 24 hours after the confluence of cells reached 80%. The culture media of the cells was removed, and the cells were washed three times in phosphate-buffered saline (PBS). Then, the cells were quickly frozen in liquid nitrogen and stored at -80 °C before extraction. Then, 1 mL 80% CH3OH/H2O (v/v) was added to the cells, and the cells were scraped with extraction solvent. Both the extract and cell/debris suspension were transferred to a clean tube and thoroughly mixed on a vortex mixer for 120 s. Ultrasonication at 30 Hz for 2 × 10 s was performed. After being allowed to settle for 10 min, the cell extraction solution was centrifuged for 15 min at 15,000 g and 4 °C. Then, 800 μL of supernatant was transferred to a new centrifuge tube for lyophilization. The residue was reconstituted with 40 μL of Mix-IS-MeOH.
