Described herein are divalent nucleobases that each binds two nucleic acid strands, matched or mismatched when incorporated into a nucleic acid or nucleic acid analog backbone, such as in a γ-peptide nucleic acid (γPNA). Also provided are genetic recognition reagents comprising one or more of the divalent nucleobases and a nucleic acid or nucleic acid analog backbone, such as a γPNA backbone. Uses for the divalent nucleobases and monomers and genetic recognition reagents containing the divalent nucleobases also are provided.
本文描述了二价核碱基,当它们被并入核酸或
核酸类似物骨架(例如γ-肽核酸(γ
PNA))中时,每个核碱基可以结合两条核酸链,无论匹配或不匹配。此外,还提供了包含一个或多个二价核碱基和核酸或
核酸类似物骨架(例如γ
PNA骨架)的
基因识别试剂。还提供了包含二价核碱基的单体和
基因识别试剂的用途。
