TriLink BioTechnologies Introduces Latest mRNA Capping Technology: CleanCap® M6 analog

Newest cap analog product improves mRNA potency with greater protein expression, offers time and cost savings, and streamlines manufacturing to drive critical therapeutic and vaccine development

SAN DIEGOTriLink BioTechnologies (TriLink), a Maravai LifeSciences company (NASDAQ: MRVI) and global provider of life science reagents and services, has launched its newest cap analog, CleanCap® M6 . The latest CleanCap analog is expected to help developers and researchers maximize the impact of their mRNA therapeutics and vaccines while reducing overall manufacturing costs, bringing life-changing medicines to market faster.

With the introduction of the CleanCap M6 technology, legacy capping methods like enzymatic and ARCA may be a thing of the past. By combining the modification of 3’OMe on the m7-Guanosine and the additional methyl modification on the +1 Adenosine, the CleanCap M6 analog is expected to improve mRNA potency with the highest protein expression of any CleanCap analog yet. Combined with technology’s single-pot reaction capabilities that shrink manufacturing times and increase mRNA yields with a purity profile of >95%, CleanCap analogs are novel mRNA Cap structures, which may improve the benefits of an mRNA therapeutic or vaccine.

“TriLink’s portfolio of CleanCap mRNA capping technology is expected to be the new go-to capping method in the very near future – it is the future,” shared Kate Broderick Ph.D., Chief Innovation Officer at Maravai LifeSciences. “What excites me most about this novel analog is its ability to make mRNA an even more powerful therapeutic than we have seen previously.”

The company’s first CleanCap analog launched in 2017 and this capping technology has been incorporated in one of the first commercially approved COVID-19 vaccines. With the introduction of CleanCap M6, TriLink has developed its most robust analog to date. Studies have shown that the innovative product increases mRNA expression by 30% or more versus enzymatic capping methods and is estimated to reduce manufacturing costs by 20-40%. *

“mRNA is clearly an emerging therapeutic modality where mRNA vaccines and therapeutics are expanding rapidly,” added Drew Burch, EVP of TriLink’s Nucleic Acid Products division. “CleanCap M6, and the entire CleanCap portfolio, joins a strong roster of synthesized nucleic acids, NTPs, and more that we expect to continue to grow.”

In addition to the CleanCap mRNA capping portfolio, TriLink has scale-up expertise and unique mRNA, oligonucleotide & plasmid production capabilities for companies focused on therapeutic, vaccine, diagnostic breakthroughs, leaning on its 25-plus years of experience to provide superior CDMO services.
