for structure-function analysis of 2'-sugar modifications including 2'-O-methyl, 2'-O-propyl, 2'-
O-pentyl, and 2'-fluoro. These modifications were analyzed for hybridization affinity to
complementary RNA and for antisense activity against the Ha-ras oncogene in cells using a
highly sensitive transactivation reporter gene system. Hybridization analysis demonstrated …
