Description: 

DSPE PEG Cy5.5 (Cy5.5-PEG-DSPE) is one of Nanocs’ fluorescent phospholipid PEG derivatives that can be used for lipid nanoparticle formulation, target tracking and detection. DSPE (1,2-distearoyl-sn-glycero-3-phosphoethanolamine) is a saturated 18 carbon phospholipid that is highly hydrophobic. PEG linker, on the other hand, offers good hydrophilicity and water solubility. Cy5.5 labeled DSPE PEG emits strong near infrared fluorescent light at 695 nm upon excited at 675 nm. Cy5.5 PEG DSPE can be easily incorporated into liposome or other lipid or phospholipid nanoparticles. Strong fluorescent signal from Cy5.5 allows quick and easy detection and tracking of labeled species. PEG linker between Cy5.5 and DSPE offers good water solubility, flexible linker structure and increased stability.
