This biotin derivative bears a terminal azide group. It can be used to prepare various biotinylated conjugates via Click Chemistry. Biotin can be subsequently detected e.g. via streptavidin or avidin. Triazole-linked adducts are showen to be highly resistant to the ubiquitous hydrolytic enzyme biotinidase and to bind avidin with dissociation constants in the low pM range.
