Diamido-dPEG?11-diamine, product number QBD-10361, is a water-soluble, homobifunctional, single molecular weight, discrete chain length polyethylene glycol (dPEG?) crosslinker that is 49 atoms (57.1 ?) long. Both ends of the crosslinker terminate with amino groups that react with activated carboxylates or their active esters to form stable amide bonds. Aldehydes and ketones react to form labile Schiff bases that are reducible to secondary amines for improved bond stability. This molecule is useful for modifying carboxylic acid-functionalized surfaces, small molecules with reactive carbonyl groups, and carbohydrates containing reducing sugars.nThe use of Diamido-dPEG?11-diamine appears in several patents. Moreover, researchers at the Karolinska Institutet, Stockholm, Sweden, reported the use of Diamido-dPEG?11-diamine in an investigation of ?-secretase and its role in Alzheimer’s Disease. Furthermore, Diamido-dPEG?11-diamine may prove useful in the following applications:nCrosslinking peptides or other small biomolecules using available carboxylic acids, aldehydes, or ketones;nIntroducing a dPEG? amine onto reducing sugars of a glycoprotein’s carbohydrate coat;nPassivating nanoparticle surfaces coated with carboxylic acids or their active esters; and,nAdding a medium-length dPEG? amine at the carboxyl terminus of a peptide.
