DSPE-Rhodamine is a red fluorescently attached phospholipid used to label liposomes. Rhodamine can be used for sample staining and is easily tracked by fluorescence microscopy. The phosphate group and polar head region of the molecule are hydrophilic (attracted to water), while the fatty acid tail is hydrophobic (repelled by water).
