Application

2-Methylnicotinic acid imidazolide (NAI or mNAI) is an RNA SHAPE probe for live-cell RNA structure profiling. SHAPE -- or selective 2′-hydroxyl acylation analyzed by primer extension -- uses small, electrophilic chemical probes to react with the 2′-hydroxyl group and provides insight to RNA structure and its dynamics in varied cells states or in cells with gene knockouts. It has also been extended to the SHALiPE approach, selective 2′-hydroxyl acylation with lithium ion-based primer extension.

RNA structure plays important roles in diverse biological processes. However, the structures of all but the few most abundant RNAs are presently unknown in vivo. Here we introduce DMS/SHAPE-LMPCR to query the in vivo structures of low-abundance transcripts. DMS/SHAPE-LMPCR achieves
