BLOG > mRNA & LNP > Product Launch Announcement: Self-amplifying RNA
We are Pleased to announce the development of a new RNA category : saRNA (Self-amplifiying RNA).
OZB saRNA have been constructed based on replicons of positive-sense ((+)-RNA) viruses (Venezuelan equine encephalitis Virus (VEEV)), where the coding sequence of the viral structural proteins is replaced with that of a gene of interest (GOI), while retaining the coding sequences of non-structural proteins (NsPs), including the viral RNA-dependent RNA polymerase.
Please note that OZB saRNAs encodes also for Puromycin Resistance Cassette, which does not alter the expression of the GOI but can be used for cell selection.
saRNAs have been designed to produce high expression level of protein with enhanced length of duration. OZB mRNAs are produced by in vitro transcription. mRNAs are stabilized at the 5’ end by modified nucleotides capping (Cap1) and contain a poly(A) tail at the 3’ end. Sequences have been optimized to yield improved stability and performance.

Photos were taken at x20 show a peak of GFP expression at 24hic mRNA GFP.
