Abstract

Structural RNA is a challenging target for recognition by hybridization probes. This chapter addresses the recognition problem of RNA amplicons in samples obtained by multiplex nucleic acid sequence-based amplification (NASBA). The method describes the design of G-quadruplex binary (split) DNA peroxidase sensors that produces colorimetric signal upon recognition of NASBA amplicons.

摘要

结构 RNA 是杂交探针识别的一个具有挑战性的靶标。本章讨论了通过多重核酸序列扩增(NASBA)获得的样品中 RNA 扩增子的识别问题。该方法描述了 G-四链体二元(分裂)DNA 过氧化物酶传感器的设计,该传感器在识别 NASBA 扩增子时会产生比色信号。
