Description:

FITC-PEG-DSPE is one of Ponsure fluorescent phospholipid PEG derivatives that can be used for lipid nanoparticle formulation, tracking and detection. DSPE (1,2-distearoyl-sn-glycero-3-phosphoethanolamine) is an 18 carbon saturated phospholipid that is highly hydrophobic. PEG backbone, on the other hand, offers good hydrophilicity and water solubility. Fluorescein labeled DSPE PEG emits strong green fluorescent light at 515 nm upon excited at 495nm. Fluorescein PEG DSPE can be easily incorporated into liposome or other lipid or phospholipid nanoparticles. Strong fluorescent signal from FITC allows quick and easy detection and tracking of labeled species. PEG linker between Fluorescein and DSPE offers good water solubility, flexible linker structure and increased stability.

Handling and Use:

FITC-PEG-DSPE  should always be kept in low temperature in dry condition. Prepare fresh solution right before use.Avoid frequent thaw and freezing. For more information about using this product,  visit www.ponsure.com.
