Biotin-11-UTP is a biotinylated uridine triphosphate that can be incorporated into short RNA strands via co-transcription with T7 RNA polymerase, and is used for synthesizing labeling reagents and detection markers. After binding to streptavidin, Biotin-11-UTP generates characteristic downward ionic current peaks during nanopore translocation, which allows the differentiation between modified and unmodified RNA. Biotin-11-UTP enables site-specific labeling of short RNA, and is suitable for single-molecule solid-state nanopore sensing detection. Biotin-11-UTP can serve as a raw material for synthesizing biotinylated single-stranded RNA probes, which is applied to rotavirus nucleic acid detection; it can also label single-stranded RNA probes targeting and immobilizing 28S ribosomal RNA in leukemia cells. Biotin-11-UTP can alter the electrophoretic mobility of transcribed RNA in agarose gels, and can be used to monitor the biotinylation degree of RNA probes .
