“…This would also be applicable for extracts of breast cancer tissue. As PESI‐MS is available for solid and liquid samples, the combination of MS analysis with existing procedures such as core‐needle biopsy and liquid biopsy will be more useful and more accurate for breast cancer screening in the future. Before clinical implementation, rigorous validation studies with different MS methods will be mandatory.…”

“…We used a DPiMS‐8060 PESI unit from Shimadzu (Kyoto, Japan), and a brief explanation of the methodology is as follows: (i) sample preparation: 2.5 mg of tissue was homogenized in 100 μL of 50% ethanol using a disposal pestle (Argos Technologies, Vernon Hills, IL, USA). (ii) The homogenate was centrifuged at 15 000 g for 5 min, and the supernatant was diluted fourfold by adding 50% ethanol 16 . (iii) A 9 μL sample of solution was placed in the sample plate (Shimadzu Corp).…”

“…The PESI‐MS analysis was performed using a triple quadrupole mass spectrometer (DPiMS‐8060; Shimadzu Corp.), which has a PESI ion source that replaces the ESI module of the original LCMS‐8060 spectrometer. The mass spectra were acquired for nonneoplastic and PDAC specimens in the positive ion mode, and all subsequent analyses were performed as previously described previously 5–9 …”
