Described herein are novel divalent nucleobases that each bind two nucleic acid strands, matched or mismatched when incorporated into a nucleic acid or nucleic acid analog backbone (a genetic recognition reagent, or genetic recognition reagent). In one embodiment, the genetic recognition reagent is a peptide nucleic acid (PNA) or gamma PNA (?PNA) oligomer. Uses of the divalent nucleobases and monomers and genetic recognition reagents containing the divalent nucleobases also are provided.
本文描述的是新型二价核碱基,它们在与核酸或
核酸类似物骨架(遗传识别试剂或遗传识别试剂)结合时,可分别与匹配或不匹配的两条核酸链结合。在一个实施方案中,
基因识别试剂是肽核酸(
PNA)或γ
PNA(?
PNA)寡聚体。此外,还提供了二价核碱基和单体的用途以及含有二价核碱基的
基因识别试剂。
