Ribozyme assays to quantify the capping
Webb29 jan. 2024 · Here, we described a method to assess the presence of the cap structure of IVT mRNAs. We designed a set of ribozyme assays to specifically cleave IVT mRNAs at a unique position and release 5'-end capped or uncapped cleavage products up to 30 nt long. WebbThe presence of the cap structure on the 5'-end of in vitro -transcribed (IVT) mRNA determines its translation and stability, underpinning its use in therapeutics. Both enzymatic and co-transcriptional capping may lead to incomplete positioning of the cap …
