RNA Synthesis

RNA Polymerases

T7 (NEB # M0251) and SP6 (NEB # M0207) RNA polymerases are DNA dependent RNA polymerases that produce DNA templated RNA transcripts. T7 and SP6 exhibit high specificity for their respective promoters. Both T7 and SP6 can be used for the in vitro synthesis of RNA for a wide variety of applications, including transfection, translation, structural studies and radioactive and non-isotopic probe generation. E. coli Poly(A) Polymerase (NEB # M0276) and Poly(U) Polymerase (NEB # M0337) generate untemplated homoribopolymeric tails on the 3´-ends of RNA. Both E. coli Poly(A) Polymerase and Poly(U) Polymerase can be used for RNA tailing for reverse transcription or labeling.

In vitro RNA synthesis requires a DNA template, RNA polymerase, NTPs and other factors. High-yield robust reactions require optimization of each reaction component. NEB offers five in vitro RNA synthesis kits, all of which have been rigorously formulated to provide reproducible high yields of quality RNA. Additionally, NEB offers a Vaccinia capping system (NEB # M0280) and a number of RNA cap analogs.
