DOPE-PEG-FITC, MW 5,000 is a PEG-lipid that features a DOPE phospholipid and an FITC fluorophore. DOPE is an unsaturated phospholipid that is commonly used to prepare lipid nanoparticles in drug delivery, while FITC is a green fluorophore with excitation and emission maxima at 491 nm and 516 nm respectively. FITC-PEG conjugates see frequent use in fluorescence microscopy, immunohistochemistry and other in vivo research applications.
