Sample Type:Blood (plasma)
Storage Conditions:-80℃
Collection Vials:EDTA-coated tubes
Storage Vials:Eppendorf tubes
Collection Tube Temp:Room temperature
Additives:EDTA

Treatment:

Treatment ID:TR002349
Treatment Summary:Plasma samples were not treated with anything prior to metabolite extraction.

Sample Preparation:

Chromatography:

Chromatography ID:CH002727
Chromatography Summary:Equilibration time was 4 min at 90% B, with 3.5 min at 0.35 mL/min, then 0.5 min at 0.25 mL/min. After sample injection, a gradient ran from 90% to 20% B over 17.5 min at 0.25 mL/min, then flow was increased to 0.35 mL/min for 1 min and held at 20% B at 0.35 mL/min for 3.5 min.

MS:

MS ID:MS003428
Analysis ID:AN003677
Instrument Name:Thermo Q Exactive HF hybrid Orbitrap
Instrument Type:Orbitrap
MS Type:ESI
MS Comments:Data were processed using Compound Discoverer 3.2 (Thermo). Minimum peak intensity was 5E5 for positive mode. Retention times were aligned across runs, quality control (QC) pooled sample areas were normalized per metabolite using a cubic spline method, requiring <50% relative standard deviation after correction for compound retention. Missing values were gap-filled based on real peak detection and metabolites with max sample area <5-fold that of the blank were censored.
Ion Mode:POSITIVE
Capillary Temperature:275
Ion Spray Voltage:+3.5 kV
Automatic Gain Control:1E6
