mRNA has become an emerging class of gene therapy because of its negligible cytotoxicity and immunogenicity. So, there is an increasing demand for efficient and robust production of mRNA molecules in both pharmaceutics and research field. In vitro transcription (IVT) is an elegant way to obtain highly pure and uniform mRNA oligonucleotides of lengths ranging from about 15 to several thousand nucleotides.https://mrna.creative-biolabs.com/category-in-vitro-transcription-vector-452.htm
