Aminooxy-dPEG®₁₁-azide.HCl (QBD-10538)



Aminooxy-dPEG®11-azide.HCl, product number QBD-10538, is a click chemistry crosslinker functionalized with an oxyamine moiety on one end of a medium-length (38 atoms), single molecular weight, discrete PEG (dPEG®) linker, and an azide group on the other end. The azide end of the linker reacts with aliphatic or cyclic alkynes through copper-catalyzed (CuAAC), ruthenium-catalyzed (RuAAC), or strain-promoted, copper-free (SPAAC) click chemistry to form a triazole ring. The molecule’s aminooxy end (sold as an HCl salt) reacts with aldehydes and ketones to form biocompatible, stable oxime bonds that are important in many bioconjugation and supramolecular construction processes.

Storage and handling-20°C; Always let come to room temperature before opening; be careful to limit exposure to moisture and restore under an inert atmosphere; stock solutions can be prepared with dry solvent and kept for several days (freeze when not in use). dPEG® pegylation compounds are generally hygroscopic and should be treated as such. This will be less noticeable with liquids, but the solids will become tacky and difficult to manipulate, if care is not taken to minimize air exposure.
