Background:

Biotin-PEG3-azide is a PEGylated version of biotin-azide that is more hydrophilic due to the incorporation of a PEGylated spacer. It can be used to label terminal alkynes via copper-catalyzed click reactions or copper-free click reactions with cyclooctynes., Biotin-PEG3-azide has been used to non-enzymatically and covalently tag proteins, which can be separated and detected using common laboratory methods such as SDS-PAGE and Western blot. It can be used in combination with other protein tags. Biotin-PEG3-azide has also been used in nanostructured biointerfaces to study ligand and receptor spacing when there are different signaling molecules present.
