Dde TAMRA Biotin Azide is a trifunctional, cleavable probe that allows for efficient recovery of avidin-bound protein complexes in affinity-based assays. This reagent contains a fluorescent dye (TAMRA) and biotin moiety linked to azide group through a spacer arm containing a hydrazine-cleavable Dde moiety. Under mild conditions (2% aqueous hydrazine), the Dde liner is cleaved, releasing the biotin tag and any avidin conjugate bound to it.
Biotin-PEG4-Dde-TAMRA-PEG3-Azide is a dye derivative of TAMRA (HY-135640) modified with a cleavable biotin group. Biotin-PEG4-Dde-TAMRA-PEG3-Azide contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
