N-(DBCO-PEG4)-N-Biotin-PEG4-NHS is a click chemistry biotinylation reagent, NHS active esters can be used to label the primary amines (-NH2) of proteins and other amine-attached macromolecule. DBCO group is very reactive with azide molecule via copper-free Click Chemistry.
N-(DBCO-PEG4)-N-Biotin-PEG4-NHS is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. N-(DBCO-PEG4)-N-Biotin-PEG4-NHS is a click chemistry reagent, it contains a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.
