    Avoiding RNase Contamination
Most eukaryotic mRNAs require a 7-methyl guanosine (m7G) cap structure at the 5´ end and a poly(A) tail at the 3´ end to be efficiently translated. The HiScribe T7 ARCA mRNA Kit (with tailing) is designed for quick production of ARCA capped and poly(A) tailed mRNA in vitro. Capped mRNAs are synthesized by co-transcriptional incorporation of Anti-Reverse Cap Analog (ARCA, NEB #S1411) using T7 RNA Polymerase. The transcription reaction can be set up easily by combining the ARCA/NTP mix, T7 RNA Polymerase Mix and a suitable DNA template. The kit also allows for partial incorporation of 5mCTP, Pseudo-UTP and other modified nucleotides into mRNA. After a brief DNase I treatment to remove the template DNA, capped mRNA is poly(A) tailed with Poly(A) Polymerase. mRNAs synthesized with the kit can be used for cell transfection, microinjection, in vitro translation and RNA vaccines.

ARCA is incorporated into mRNA exclusively in the correct orientation, generating capped mRNA that is more efficiently translated. Standard cap analogs can be incorporated in either direction resulting in only 50% of capped mRNA that is functional in protein translation.

Methylation at the 3´ position of 7mG forces the cap structure to be attached to mRNA in the correct orientation.

Notes
  • All kit components should be stored at –20°C. The kit contains sufficient reagents for 20 reactions of 20 μl each. Each standard reaction yields up to 20 μg of capped mRNA from 1 μg control template. Up to 25 μg capped and tailed mRNA can be obtained after Poly(A) tailing and purification by LiCl precipitation.
