Azide-PEG4-Sulfo-Link-biotin, TEA salt serves as a unique PEG linker containing a biotin group, sulfo group, and terminal azide. Biotin is useful for affinity-based applications such as pull-down assays or for ligating with streptavidin proteins. The azide can undergo copper-catalyzed Click Chemistry reactions with alkyne, DBCO, and BCN. The inclusion of a PEG linker as well as the sulfo group in this molecule improves its aqueous solubility.
