(a, b) Mass chromatogram of eight most abundant PG and lysylPG species from S. aureus and S. epidermidis are depicted. (c) The detected PGs and lysylPGs by the QToF mass spectrometer are summarized. The quantity (ng) of each lipid species in injected total lipid extracts (5 µg) was determined by curve fitting of the chromatogram area to the external standard curve. The measurements were performed in triplicate (mean ± SD).
