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.
