Biotin-XX, SE (6-((6-((Biotinoyl)Amino)Hexanoyl)Amino)Hexanoic Acid, Succinimidyl Ester)

The amine-reactive biotin-XX, SE can be used to attach this important hapten to biomolecules of interest for subsequent detection with streptavidin, avidin or NeutrAvidin™ biotin-binding protein. This molecule has a 14 atom spacer designated by 'XX' to facilitate reactivity with the molecule and eventual accessibility of the biotin to avidin or streptavidin.
