DSPE-PEG-Fluor 488, MW 2000

DSPE-PEG-Fluor 488, MW 2000 is a PEG-dye-lipid conjugate consisting of DSPE phospholipid and Fluor 488 dye. DSPE is a phospholipid that spontaneously forms micelles in aqueous media, while Fluor 488 is a cyanine dye widely used in fluorescence microscopy with excitation and emission maxima at 499 nm and 520 nm, respectively. Polyethylene glycol lipids are commonly utilized to stabilize lipid nanoparticles.
