Aminooxy-PEG5-azide Usage And Synthesis

Description

Aminooxy-PEG5-azide is a biolabeling reagent comprising an aminooxy group and an azide group. The hydrophilic PEG spacer increases solubility in aqueous media. The aminooxy group can be used in bioconjugation. by reacting with an aldehyde moiety to form an oxime bond, if a reductant is used, it will form a hydroxylamine linkage. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

Uses

Aminooxy-PEG5-azide is a PEG-based PROTAC linker can be used in the synthesis of PROTACs[1]. Aminooxy-PEG5-azide is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
