Identification of a Widespread Palmitoylethanolamide Contamination in Standard Laboratory Glassware
Laboratory studyOther animals
- Design
- Laboratory study
- Subjects
- Not applicable; an analytical study of laboratory glassware contamination
- Dose used in the study
- Not applicable; no PEA was administered, this is a measurement-artefact study
- Duration
- Not stated in the abstract
- What was measured
- PEA-like contamination in new glass Pasteur pipettes, by liquid chromatography-tandem mass spectrometry and accurate mass analysis.
What the authors reported
New 5.75-inch glass Pasteur pipettes, commonly used for lipid extraction, contained high levels of a contaminant indistinguishable from PEA. This artefact could explain discrepancies in reported PEA levels in human blood serum and other tissues, the authors say.
Limits of this study
A laboratory methods study, not a treatment or clinical study; it says nothing about PEA's biological effects. Authors declare no competing financial interests.
