Streptavidin is a biotin binding protein and consists of four identical subunits, each of which binds one molecule of biotin. Streptavidin and biotin are routinely conjugated to indicator enzymes for use in diagnostic kit development and manufacturing. Unlike avidin, streptavidin does not contain a carbohydrate moiety which minimizes non-specific binding.
