Description: OUN38775, also known as 5S rRNA modificator, is a rRNA modification agent. 5S rRNA modificator worked as an electrophile for 2’-hydroxyl acylation on structured RNA molecules, yielding accurate structural information comparable to that obtained with existing probes; 5S rRNA RNA modification. This product has no formal name at the moment. For the convenience of communication, a temporary code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming).
