Study ID | ST001213 |
Study Title | Serum lipidomic profile of cold-exposed Ucp1cre/12-LOX KO mice |
Study Summary | We aimed to evaluate whether specific deletion of 12-Lipoxygenase (12-LOX) in brown fat can affect the serum concentrations of 12-LOX products under cold exposure. |

Sample Preparation:
Sampleprep ID: | SP001288 |
Sampleprep Summary: | Aliquots of 100 µL serum or 1mg protein from homogenized tissue (measured by BCA) were taken, depending on the experiment. 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 31 −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 H 2 O (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:H 2 O (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 LCMS/MS mediator lipidomics platform. |
