In vitro Synthesis (IVT)

In vitro synthesis of single-stranded RNA molecules is a widely used laboratory procedure that is critical to RNA research, as well as to RNA biopharmaceuticals. This technique is versatile in that it allows the researcher to tailor synthesis and introduce modifications to produce a transcript. Downstream applications include biochemical and molecular characterization of RNA for RNA-protein interactions and structural analyses, generation of RNA aptamers, synthesis of functional mRNAs for expression, and generation of small RNAs for alteration of gene expression (e.g., guide RNAs, RNAi). Furthermore, the use of in vitro synthesized RNA has been instrumental in the development of RNA vaccines and CRISPR/Cas9 genome editing tools, generation of pluripotent stem cells, as well as development of RNA amplification-based diagnostics.

High-yield robust IVT reactions require optimization of each reaction component. NEB offers six in vitro RNA synthesis kits, all of which have been optimized to generate reproducible yields of quality RNA. In addition, individual components can also be purchased for IVT and mRNA capping.
