Polynucleotides containing abasic, cleavable sites are provided. These polynucleotides are useful in a variety of biochemical and chemical contexts, particularly in solid phase nucleic acid hybridization assays because a captured probe can be released from the support. The polynucleotides have the structure ##STR1## where R is selected from the group consisting of 2-nitrobenzyl, 4-penten-1-yl, ##STR2## where R', R.sub.i and R.sub.j are as defined herein. One of the preferred embodiments is a polynucleotide where R is ##STR3##
提供含有脱氧核糖核苷酸的多聚核苷酸,其中含有可切割位点。这些多聚核苷酸在各种生化和化学环境中非常有用,特别是在固相核酸杂交分析中,因为捕获的探针可以从支持物中释放出来。这些多聚核苷酸的结构为##STR1##其中R是从2-硝基苯基、4-戊烯-1-基中选择的,##STR2##其中R'、R.sub.i和R.sub.j如此定义。其中一个首选实施例是一种多聚核苷酸,其中R为##STR3##
