Dde TAMRA Biotin Azide is a trifunctional, cleavable probe that allows for efficient recovery of streptavidin and avidin-bound protein complexes in affinity-based assays. This probe contains a fluorescent dye (TAMRA) and biotin moiety linked to azide group through a spacer arm containing a hydrazine-cleavable Dde moiety. in aqueous hydrazine, the Dde linker is cleaved, releasing the biotin tag and any streptavidin and avidin conjugate bound.
