BDP® TR tetrazine

BDP TR is a borondipyrromethene fluorophore for the ROX channel. The dye produces bright fluorescent emission. Tetrazines are reactive components for the conjugation with strained cycloalkenes.

AmdU (5-Azidomethyl-2'-deoxyuridine)

Azidomethyldeoxyuridine (AmdU) is an azide-contained nucleoside that is incorporated into nascent DNA by cellular polymerases. The azide groups attached to DNA this way can be subsequently modified with alkynes or cycloalkynes via copper-catalyzed or strain-promoted click reaction.
