DSPE-PEG-Maleimide, MW 5,000 is a maleimide PEG polymer. The DSPE group is a phospholipid that is used as a self-assembling reagent to prepare PEGylated liposome or micelle. Maleimides react with thiols between pH 6.5 to 7.5. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose.
