Improvements are disclosed for in vitro selection methods that yield ligands and catalysts through partitioning libraries of oligonucleotides. These improvements all increase the diversity and amount of fuctionality available to the oligonucleotides, by incorporating into the oligonucleotide libraries non-standard nucleobase analogs and/or functionalized standard nucleobases, and/or incorporating into the selection mixture organic cofactors that deliver functional groups by binding non-covalently to oligonucleotides in the library.
本文披露了改进的体外选择方法,通过对寡核苷酸库进行分区,可以产生
配体和催化剂。这些改进都增加了寡核苷酸库中可用的多样性和功能量,通过将非标准核碱基类似物和/或功能化标准核碱基引入寡核苷酸库中,并/或将有机辅因子引入选择混合物中,通过非共价结合到寡核苷酸库中,传递功能基团。
