Product profile
2'-O-4'-C-Locked-rA(Bz) is classified as base-protected nucleosides (Formula C18H17N5O5; molecular weight 383.40).
2'-O-4'-C-Locked-rA(Bz) is useful for high-affinity probes, SNP/mismatch-discrimination studies, antisense designs and short sequence probes.
For 2'-O-4'-C-Locked-rA(Bz), high-affinity monomers require careful positional design; over-substitution may increase off-target binding or complicate synthesis.
