Collection:
Collection ID: | CO001268 |
Collection Summary: | Mice were anaesthetised with Avertine and blood was collected through cardiac puncture. Samples were let in room temperature for 30 minutes, and then centrifuged for 3 minutes at 14,000RPM. Serum fas collected and frozen at -20C for further lipidomics analysis. |
Sample Type: | Blood (serum) |
Storage Conditions: | -80℃ |
Treatment:
Treatment ID: | TR001289 |
Treatment Summary: | Mice were injected i.p. 15 minutes before the cold exposure, with 50ul of DMSO (vehicle) or LOXBlock-1. Then, the animas were placed in 5C or 22C temperature for 4 hours, until the samples were collected. |
Sample Preparation:
Sampleprep ID: | SP001282 |
Sampleprep Summary: | Aliquots of 100 µL serum were taken and a mixture of deuterium-labeled internal standards was added to each aliquot, followed by 3x volume of sample of cold methanol (MeOH). Samples were vortexed for 5 minutes and stored at −20 °C overnight. Cold samples were centrifuged at 14,000g for 10 minutes, and the supernatant was then transferred to a new tube and 3 mL of acidified H2O (pH 3.5) was added to each sample prior to C18 SPE. The methyl formate fractions were collected, dried under nitrogen, and reconstituted in 50 µL MeOH:H2O (1:1, by vol). Samples were transferred to 0.5 mL tubes and centrifuged at 20,000g at 4 °C for 10 minutes. (35ul) of supernatant was transferred to LC–MS/MS vials for analysis using the BERG LC–MS/MS mediator lipidomics platform. |

MS Comments: | MS spectra were acquired in high-resolution mode (>30,000) using a 100-ms accumulation time per spectrum. Full-scan MS/MS was acquired in high sensitivity mode, with an accumulation time optimized per cycle. Collision energy was set using rolling collision energy with a spread of 15V. The identity of a component was confirmed using PeakView® software (SCIEX), and quantification was performed using MultiQuant™ software (SCIEX). C18SPE cartridges were purchased from Biotage. All solvents were of HPLC or LC-MS/MS grade and were acquired from Sigma-Aldrich, Fisher Scientific, or VWR International. |
