Collection:
| Collection ID: | CO003053 |
| Collection Summary: | Mouse liver tissues were extracted, kept on ice and sent immediately to the the Centre of Panoromic Sciences (The University of Hong Kong) for testing |
| Collection Protocol Filename: | untargeted_protocol.pdf |
| Sample Type: | Liver |
| Storage Conditions: | On ice |
Treatment:
| Treatment ID: | TR003069 |
| Treatment Summary: | Samples did not receive any treatment. |
Sample Preparation:
| Sampleprep ID: | SP003066 |
| Sampleprep Summary: | As described in the provided protocol (see attached file): - "2mL chloroform:methanol (2:1, v/v) was added to user provided tissue. The sample was then sonicated under ice chilled probe sonicator for 20 sec, cooled down for 10 sec and another sonication for 20 sec. The sample was then centrifuged at 3000 g for 5 min. Supernatant was aliquot out and dried under nitrogen.The sample was then reconstituted with IPA:MeOH:chloroform (1:1:0.2, v/v) in 1mg to 5uL. Then, 3 μL was injected into the LC-MS/MS system." |

| Instrument Name: | Thermo Orbitrap Exploris 120 |
| Instrument Type: | Orbitrap |
| MS Type: | ESI |
| MS Comments: | The mass spectrometry analysis was processed using an Orbitrap Exploris 120 mass spectrometer Thermo Fisher (Waltham, MA, USA) equipped with a HESI II probe in polar switching mode with source parameters set as follows: sheath gas flow rate, 60; auxiliary gas flow rate, 17; sweep gas flow rate, 1; spray voltage,+3.5/-3.0 kV; capillary temperature, 275 oC; S-lens RF level, 70; and heater temperature, 325 °C. Data was collected at dd-MS2 mode. Data analysis was performed using Lipidsearch (Thermofisher Scientific/Mitsui Knowledge Industries) with the default parameters for Orbitrap MS Product Search and Alignment. After alignment, raw peak areas for all identified lipids were exported to Excel files. |
