The 5′ cap is essential to the stability and translation of mRNA, and enzymatic capping is a widely used way to add it to in vitro transcribed (IVT) mRNA. The capping reactions depend on a methyl donor: the methyl groups that form the Cap 0 and Cap 1 structures are supplied by S-adenosylmethionine (SAM), so the quality and consistency of the SAM raw material affect the capping step directly. S-Adenosylmethionine (SAM) is a methyl donor substrate developed for enzymatic mRNA capping and nucleic acid drug manufacturing. As an essential methyl group donor, it supports the efficient formation of the 5′ Cap 0 and Cap 1 structures, which helps improve capping efficiency, maintain mRNA structural integrity, and support the translation performance of the final mRNA product.
The product is manufactured in a GMP-compliant production environment with a fully animal-origin-free process, and it is designed for high quality, batch consistency, and reliable performance in mRNA development and commercial production. It is high purity, with strict impurity control and ultra-low metal residue levels, to meet the demanding requirements of mRNA manufacturing. It is compatible with various commercial capping enzymes and 2′-O-methyltransferases, so it can be integrated into existing IVT mRNA capping workflows, from preclinical research to large-scale GMP manufacturing. DMF filing support is available, and flexible supply options and customized requirements are supported.
