DBCO-PEG4-Biotin是一种含生物素基团和4个PEG的azadibenzocyclooctyne-biotin衍生物。DBCO-PEG4-Biotin是一种用途广泛的生物素酰化试剂，能通过无铜催化烷基叠氮化反应(SPAAC)将生物素的一部分引入叠氮标记的生物分子中。
DBCO-PEG4-Biotin is an azadibenzocyclooctyne-biotin derivative containing a biotin group and 4 PEGs. DBCO-PEG4-Biotin is a versatile biotinylation reagent used for the introduction of a biotin moiety to azide-labeled biomolecules via copper-free strain-promoted alkyne-azide click chemistry (SPAAC) reaction[1].
The alkyne group can react with azide moiety in copper-free Click Chemistry reaction to form a stable triazole linkage.
