Photochromic nucleoside (PCN) phosphoramidite that provides reversible duplex regulation via a light induced trans-cis isomerization.
Universal base phosphoramidite.
Useful amino-modified deoxyadenosine phosphoramidite.
Useful for incorporating 7-Deaza-modified guanosine into oligonucleotides to disrupt unwanted hydrogen bonding.
Convertible nucleoside phosphoramidite that allows the formation of N4-alkyl-C residues in RNA for structural studies.
Des-methyl analog of cytidine useful for probing the hydrogen-bonding characterisitcs in oligonucleotides.
Features a nucleobase that is isosteric with adenine but offers a different pi-electron distribution.
Useful addtion to the nebularine family for hydrogen bonding studies.
Useful phosphoramidite for oxidative studies of thymidine.
Phosphoramidite enables incorporation of a nitrogen atom in place of the methine group at position 6 of the thymine ring in oligonucleotides.
