Vaccinia Capping Enzyme
7-methylguanylate cap structures (Cap-0) are essential for efficient translation of in vitro-transcribed RNA in eukaryotic expression systems. Vaccinia Capping Enzyme provides all the components necessary to add Cap-0 structures to the 5′ ends of uncapped RNA. RNA transcripts can be capped in less than one hour in the presence of the capping enzyme, reaction buffer, GTP, and a methyl donor.

The use of the Vaccinia Capping Enzyme in the same reaction with mRNA Cap 2′-O-Methyltransferase (Cat. # 2470) generates Cap-1 RNA. Cap-1 RNA has a methyl group at the 2'-O position of the first nucleotide adjacent to the cap structure at the 5´ ends of the RNA. This capping modification reduces the innate immune response to in vitro transcribed RNA when it is used in vivo.
Overview
A complete solution for enzymatic capping of in vitro-transcribed mRNAs.
- Add 7-methylguanylate cap structures (Cap-0) to the 5′ ends of uncapped RNA
- Use together with Cap 2′-O-Methyltransferase (Cat. # 2470) to generate Cap-1 RNA
- Save on reaction costs when you purchase the larger size
- Absent of nuclease activity
More Information
Applications
- Enzymatic capping of in vitro-transcribed mRNA prior to translation
- Labeling 5′ ends of mRNA
Source
Escherichia coli that harbor plasmids containing the genes for the vaccinia virus capping enzyme.

Speed up your vaccine development with innovative technologies
Vaccines have significantly decreased the burden of infectious diseases worldwide since the development of the first vaccine more than 200 years ago that led to the eradication of smallpox. In recent years, the spread of severe infections has highlighted the critical need for the rapid development of vaccines against previously unknown pathogens to deal with pandemics such as COVID-19.
