Collection:

Collection ID:CO003356
Collection Summary:Spleen samples from mice subjected to myocardial infarction (MI) surgery were extracted with liquid–liquid extraction.
Sample Type:Spleen
Storage Conditions:-80℃

Treatment:

Treatment ID:TR003372
Treatment Summary:No treatment

Sample Preparation:

Sampleprep ID:SP003370
Sampleprep Summary:50 mg of spleen tissues was homogenized with methanol (2% formic acid and 0.01 mol/L BHT) spiked with internal standard mixture. After centrifugation, the supernatant was added to water and ethylacetate, and the sample was mixed and centrifuged at 12,000 × g. The upper organic phase was transferred to a new tube, and the water phase was extracted again. The organic phase was combined and then evaporated to dryness and further dissolved in 100 μL of 30% acetonitrile. After vigorous mixing, samples were filtered by use of centrifuge tube filters (nylon membrane, 0.22 μm).

MS:

MS ID:MS005044
Analysis ID:AN005314
Instrument Name:ABI Sciex 5500 QTrap
Instrument Type:QTRAP
MS Type:ESI
MS Comments:Arachidonic acid metabolites were quantified by use of a 5500 QTRAP hybrid triple quadrupole linear ion trap mass spectrometer (AB Sciex, Foster City, CA, USA) equipped with a Turbo Ion Spray electrospray ionization source. The mass spectrometer was operated using the software Analyst 1.5.1. Analytes were detected using multiple reaction monitoring (MRM) scans in negative mode. The dwell time used for all MRM experiments was 25 ms. The ion source parameters were set as follows: CUR  =  40 psi, GS1  =  30 psi, GS2  =  30 psi, IS  =  −4500 V, CAD  =  medium, and temp  =  500°C. Metaboanalyst 3.0 (http://www.metaboanalyst.ca) was used for metabolomic data analysis.
