Stearic acid-PEG-Mal, MW 3,400 is a lipophilic thiol-reactive PEG polymer. The stearic acid can be used to encapsulate hydrophobic therapeutic agents while the PEG chain increases overall water solubility and biocompatibilty. Reaction between maleimide and thiol generates thioether linkage. Reagent grade, for research use only.
