Aims: To clarify the stability of blood proteins during pre-analytical blood processing and storage, to compare the proteomes of similarly treated serum and plasma samples.

Methods: We compared plasma samples prepared by centrifugation after storage of blood at room temperature for 0, 15 or 30 minutes, or under refrigeration at 0-5°C for 1, 4 or 8 hours. We also compared protein levels between plasma and serum. The plasma and serum samples were digested by trypsin and analyzed by mass spectrometer.

Participants/Materials: Plasma and serum samples from heathy individuals

Plasma: 18 samples from 3 heathy individuals

Serum: 3 samples from 3 heathy individuals

Targets Mass Spectrometry
Source Plasma and serum samples
Sample Preparation Method Blood samples collected from three healthy Japanese volunteers were completely coagulated at room temperature and centrifuged to prepare serum. Matching blood samples from the same volunteers were centrifuged to obtain plasma immediately or after storage at room temperature or at 0-5°C for different periods. The serum and plasma samples were mixed with sodium deoxycholate and N-lauroylsarcosinate, reduced with dithiothreitol, alkylated with iodoacetamide, and digested with lysyl endopeptidase a and then with trypsin. The digested samples were desalted using GL-Tip GC and SDB.

Acquisition Method for Identification: Information Dependent Acquisition

Acquisition Method for Quantification: SWATH (Data Independent Acquisition)

Peak Detection / Protein Identification Method For protein identification, data was acquired in a data-dependent acquisition mode, and analyzed by ProteinPilot 4.5 (Sciex) with the Uniprot human reference proteome database (release 2017_06). The peptide identification confidence for the dataset was evaluated versus the false discovery rate (FDR). For protein quantification, data was acquired in the data-independent acquisition mode (SWATH) with a variable precursor ion window, and analyzed by Skyline-daily 3.7 with an in-house spectral library. The target peptide peaks were identified with less than 1% FDR, and all peaks were manually inspected. The levels of proteins were calculated based on the sum of the peak areas of unique unmodified tryptic peptides without miscleavage.
