While most modifications to RNA are built for maintenance, demand in new and improved compounds is growing for various use of synthetic RNA. A major one is gRNA for recent CRISPR/CAS9 systems, but the more veteran application for RNA modifiers is undoubtedly antisense RNA. In order to harness the mechanistic advantages of RNA interference,  custom nucleotide sequences need to be equipped with the ability to permeate cell walls, bind to the target and protect itself from degradation. We offer an advanced selection of 2’-O-alkyl/methyl compounds along with affinity and fluorescent labels to follow a sequence in experiments all throughout its development.
