title: Convenient RNA synthesis using a phosphoramidite possessing a biotinylated photocleavable group.
abstract: A convenient RNA synthesis using a biotin-streptavidin interaction and a photocleavable protecting group is described. The biotinylated photocleavable group was introduced at the 2'-position of the uridine derivative. Using the phosphoramidite 12, we attempted the synthesis of a 21mer RNA, which is pure enough to show potent RNAi activity compared with a conventionally prepared and HPLC-purified 21mer RNA with the same sequence.
