Webb22 maj 2024 · Up to seven different SHAPE chemical probes have been reported, with variations in their half-lives ranging from 0.25 s to 73 min [14,15, 23, 26] (Table 2). WebbSHAPE chemistry exploits the reactivity of the RNA ribose 2′-OH group using small hydroxyl-selective electrophilic reagents. In contrast to other chemical probing techniques, SHAPE reactivities detect and quantify local nucleotide flexibility and dynamics, ignoring base identity [23] [24] [25] [26] [27] [28] [29] [30] .
Webb3 juni 2011 · In the SHAPE-seq approach used by Lucks et al. (10), three processing steps are used to detect modification sites: (i) reverse transcriptase-mediated primer extension, for which there is now an authoritative approach for extracting the probability of RNA modification (9); (ii) a single-stranded DNA ligation step; and (iii) PCR.
