Features and Benefits

MAL-dPEG4-Glu(TFP ester)-NH-dPEG4-Glu(TFP ester)-NH-m-dPEG24 is a novel, patent-pending Sidewinder™ product from Quanta BioDesign that permits attachment of hydrophobic groups on the sidearms of two glutamic acid moieties. Short hydrophilic spacers separate the glutamates, and a long hydrophilic dPEG unit terminates the construct. A sulfhydryl-reactive maleimide group provides an attachment point for the construct to another molecule, such as a protein or peptide. Tetrafluorophenyl esters functionalize the two glutamate units along the Sidewinder™ backbone.
