Abstract

The secondary ion mass spectrometry (SIMS) imaging of single paramecium and rat pheochromocytoma (PC) cells was described. Images of paramecia were collected using the latest freeze techniques. It was found that fragments of common membrane lipids, including phosphatidylcholine at 184 m/z and phosphatidylethanolamine at 142 m/z were localized to the cells. The images demonstrated the ability of the time of flight SIMS imaging to analyze phospholipids in single cell membranes.
