RNA products & Services
Catalogue RNA – Premade mRNA, circRNA & saRNA
Researchers seeking to accelerate their studies can choose from an extensive catalogue of pre-made RNA products, including a comprehensive catalogue of premade RNA products, including mRNA, circRNA, and saRNA. All are incorporated with EZ Cap (Cap1) or ARCA (Cap0), polyA Tail and Modified Nucleotides(e.g. pseudo-UTP, 5-moUTP) and validated to ensure high integrity, potency in performance in a variety of applications.

In vitro Transcription
HyperScribe™ In Vitro Transcription Kits provide rapid, high-yield synthesis of high-quality RNA for research applications. Optimised for performance and reproducibility, these kits support the production of mRNA, sgRNA and labelled RNA using T7, SP6 or T3 RNA polymerase systems. These kits are designed to simplify workflow implementation whilst maintaining excellent transcript integrity and yield.
Modified Nucleotides
We offer a broad range of modified nucleotides for in vitro transcription applications, enabling researchers to improve RNA stability, enhance translation efficiency and reduce innate immune responses. The portfolio includes commonly used modifications such as pseudo-UTP and N1-methyl-pseudo-UTP, together with fluorescently labelled and biotin-labelled nucleotides for RNA tracking, imaging and detection application
Custom RNA Synthesis Services
Custom RNA synthesis services are available in microgram to gram scale to support a wide range of research applications, from early-stage discovery to therapeutic development. Researchers can choose from linear mRNA, circRNA and saRNA formats, with options for sequence optimisation, nucleotide modification, capping and poly(A) tailing and can be combined with downstream LNP encapsulation for a complete RNA production workflow.
