In vitro transcription of mRNA with the NEB HiScribe™ SP6 Quick RNA Synthesis Kit and subsequent enzymatic capping v1

CRChristian CR RenickeJohns Hopkins University

Key Points

A single in vitro transcription reaction produces between 60 and 160 µg mRNA, facilitating gene expression research.
Using a simple cap0 5' structure combined with a 50 nt polyA tail achieved optimal expression efficiency in Aiptasia zygotes.
This protocol highlights the application of SP6 RNA polymerase and enzymatic capping for synthesizing mRNA in various organisms.
Efficient mRNA synthesis and capping may advance studies on mRNA functionalities in diverse biological systems.

Abstract

This a protocol for in vitro transcription (IVT) of mRNA with SP6 RNA polymerase (with or without template-based polyA-tail) followed by enzymatic capping. A single reaction should produce between 60 and 160 µg mRNA. The protocol was used to produce mRNA of different fluorescent proteins for electroporation of Aiptasia (Exaiptasia diaphana) zygotes. There, a simple cap0 5′ structure and a polyA tail of 50 nt proved most efficient for expression in vivo, this might be different in other organisms.
