Shape chemical probing
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] . Webb6 dec. 2024 · The selective 2’-hydroxyl acylation analyzed by primer extension (SHAPE) chemical probing method provides information about RNA structure and dynamics at …
