DSPE-PEG-Fluor 488, MW 2,000 is a powerful labeling dye and PEG polymer with hydrophilic phosphate head and hydrophobic lipid tails. The dye has an excitation peak at 499 nm and an emission peak at 520 nm. The polymer can self-assemble to form lipid bilayer in water. The phospholipid polyPEG can be used as a drug nanocarrier for administration of nutrients and therapeutics. BP Fluor 488 is a pure 5-sulfonated rhodamine molecule and it eliminates the lot-to-lot variation caused by two isomers' ratio differences. Reagent grade, for research purpose.
