  • One key advancement to develop so-called drugable mRNAs was the preparation of chemically modified mRNAs, e.g. by capping. The introduction of modified nucleobases such as Anti-Reverse Cap Analog (ARCA) was the foundations for clinical usage of mRNAs. The half-life of the mRNA and the translation efficiency is increased by using this cap analog used during in vitro transcription for the generation of capped transcripts.
