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:	CO001946
Collection Summary:	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:	Mouse feces and liver
Storage Conditions:	-80℃

Treatment:

Treatment ID:	TR001965
Treatment Summary:	No treatment

Sample Preparation:

Sampleprep ID:	SP001959
Sampleprep Summary:	Faecal samples were collected and immediately stored at -80 °C for further analysis. After the mice were sacrificed, liver tissue was sampled, immediately frozen in liquid nitrogen, and then stored at -80 °C. The study was approved by the Animal Ethics Committee of Saiye Biology (ACU20-A027). Mouse liver tissue (20 mg) and 600 μL CH3OH/H2O (8:2, vol/vol) solvent were combined in a centrifuge tube and then homogenized (28 Hz, 60 s and 30 s) in a frozen mixed ball grinding machine (MM400, Retsch Technology, Han, Germany). The mixture was centrifuged for 10 min at 15,000 g and 4 °C, 500 μL of supernatant was transferred to a new centrifuge tube for lyophilization, and the residue was reconstituted with 100 μL of Mix-IS-MeOH. Mouse faeces: A 60 mg sample of mouse faeces and 600 μL CH3OH/H2O (8:2, vol/vol) solvent were combined in a centrifuge tube and then homogenized (28 Hz, 60 s and 30 s) in a frozen mixed ball grinding machine (MM400, Retsch Technology, Han, Germany). The mixture was centrifuged for 10 min at 15,000 g and 4 °C; then, 500 μL of supernatant was transferred to a new centrifuge tube for lyophilization, and the residue was reconstituted with 100 μL of Mix-IS-MeOH.
