Fluorescein DHPE
Fluorescein DHPE is a phospholipid that is labeled on the head group with the bright, green-fluorescent fluorescein dye. Because of fluorescein's photolability, fluorescein DHPE is a useful reagent for measuring lateral diffusion in membranes using fluorescence photobleaching recovery methods. Fluorescein DHPE has also been used in conjunction with polyclonal anti-fluorescein dye antibody to prepare colloidal gold probes for SPT diffusion measurements in supported phospholipid bilayers and in keratocyte plasma membranes.
