DSPE-PEG-PA, MW 2,000 functions as a PEG polymer containing DSPE and a carboxylic acid end group. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The hydrophilic PEG increases the water solubility of the overall compound allowing for the delivery of the drug. The carboxylic group can undergo sequential amide coupling reaction with amine-bearing biomolecules in the presence of EDC or HATU. Reagent grade, for research purpose.
