Modifications for enzymatic coupling of oligonucleotides to proteins

Benzylguanine und Benzylcytosine

Triglycin (Gly-Gly-Gly) for sortase-mediated linking reaction
5'-Hydrazide Modification: Reactive Linker
An efficient way to link oligos to other biomolecules is the hydrazide-aldehyde coupling. Aldehydes represent highly reacted carbonyl compounds that can react with hydrazides under neutral or slightly acidic conditions to form stable hydrazone conjugates in a fast and efficient way. Thus, a conjugation of oligonucleotides to other (bio)molecules can be achieved easily under physiological conditions.
