From: A lipidomic approach to the study of human CD4+ T lymphocytes in multiple sclerosis
MALDI-TOF mass spectra of lipids from CD4+ T lymphocytes obtained in positive and negative mode. Representative MALDI-TOF mass spectra of lipids extracted from CD4+ T lymphocytes (upper panels) prepared by the Bligh and Dyer procedure. Spectra were acquired in both negative (a) and positive (b) mode, using the 9-AA matrix by averaging 2.000 consecutive laser shots. MALDI-TOF spectra of 9-AA matrix detected in negative (c) and positive mode (d) is reported. Spectra were acquired using a Ultraflex Extreme MALDI-TOF/TOF (Bruker).
