Nucleic sequences used in this study.

5′ and 3′ subscripts indicate sequences in the 5′-3′ and 3′-5′ orientations, respectively. Sequences are aligned, and abasic sites (AS) are labeled in red with their positions. PCR primers Rup_For5′ and Rup_Rev3′ and their alignment to target sequences are also represented. SERRS capture probe, detection probe and 3 blockers are labeled Cap3′, Det3′, Block15′, Block25′ and Block35′, respectively.Nucleic sequences used in this study.
