COUMARIN DERIVATIVES FOR USE AS NUCLEOTIDE CROSSLINKING REAGENTS

摘要

A photoactivatible nucleoside analogue is disclosed, comprising a coumarin moiety linked through its phenyl ring to the 1-position of a ribose or deoxyribose sugar moiety. The resulting nucleoside analogue is typically used as a photocrosslinking group when inserted into a polynucleotide as a replacement for one or more of the complementary nucleoside bases present in a probe used in a hybridization assay.
