Study IDST001830
Study TitleExhaustive analysis of endogenous oxPCs in APAP-treated mice.
Study SummaryA single dose of APAP at 300 mg/kg body weight was intraperitoneally administered into eight-week-old C57BL/6J male mice. After extraction of hepatic lipids, oxPCs were analyzed by LC/HRMS/MS. All mass spectrometry raw data obtained in this study were deposited.

Sample Preparation:

Sampleprep ID:SP001913
Sampleprep Summary:Hepatic lipids were extracted from the liver samples according to the modified Bligh and Dyer method. Briefly, 1 mL of extraction solution (methanol:chloroform:water = 5:2:2) containing 100 μM dibutylhydroxytoluene, 100 μM ethylenediaminetetraacetic acid, and 100 nM PC15:0/18:1-d7 was added to a frozen tissue sample (wet weight: approx. 50 mg), and then, the sample was homogenized using a Macro Smash homogenizer. Subsequently, the extraction solutions were sonicated on ice bath for 5 min. After centrifugation (6,000 g, 10 min, 4°C), 700 µL of the supernatant was collected, and then, 235 µL chloroform and 155 µL water were added to the supernatant. The organic layer was collected in a glass tube and dried under a stream of nitrogen gas; the dried residue was dissolved in methanol (200 µL) and stored at −80 °C before performing the LC/HRMS/MS experiments.
