Phosphoramidite used to incorporate a 2-amino-modified deoxyadenosine into an oligonucleotide.

Classic protected DNA nucleoside phosphoramidite.

Phosphoramidite for the incorporation of an abasic nucleoside into oligonucleotides that offers Click Chemistry capabilities.

Useful modified deoxyctidine phosphoramidite.

After incorporation into an oligonucleotide, irradiation at 365 nm at neutral pH causes strand cleavage, leaving phosphate groups on both daughter strands.

Phosphoramidite useful for synthesising 2'-5' linked oligonucleotides.

Allows for incorporation of a halogenated nucleoside into oligonucleotides for crystallographic studies and crosslinking studies of protein-DNA and RNA-DNA complexes.

Phosphoramidite for incorporation of Biotin with a dT nucleobases, internally or at the 5' end of an oligonucleotide.

Phosphoramidite for the incorporation of a ribo abasic spacer internally or at the 5' end of an oligonucleotide.

Convertible nucleoside phosphoramidite that allows the formation of N4-alkyl-C residues in RNA for structural studies.
