现有的检测假尿苷(Pseudouridine,PGD)的方法主要使用CMCT标记或放射性标记。本文描述了一种灵敏且定量的方法,用于不需要这种标记的抗体检测。这种方法结合了10-23 DNA酶的选择性,可以区分尿苷(U),滚环扩增(RCA),以增加测定的灵敏度。
Existing methodologies for detecting Pseudouridine (Ψ) mostly use CMCT labeling or radiolabeling. Described herein is a sensitive and quantitative method for Ψ detection that does not need this labelling. This approach combines the selectivity of a 10–23 DNAzyme, which can distinguish Ψ from uridine (U), with rolling circle amplification (RCA) to increase the sensitivity of the assay.
