Biological Activity

DBCO-PEG4-Biotin is a biotinylation reagent for labeling azide-containing biomolecules via Cu(I)-free Strain-Promoted Alkyne-Azide Click Chemistry (SPAAC) reaction. The hydrophilic PEG4 linker reduces or eliminates aggregation and precipitation during the labeling process by increasing the hydrophilicity of the target molecule. The PEG linker in DBCO-PEG4-Biotin also enhances the accessibility of the biotin moiety, improving the detection efficiency of the biotinylated molecule via fluorescent or HRP-labeled streptavidin or its affinity purification via streptavidin agarose.
