Product Overview

（图片待提供）

S-Adenosylmethionine (SAM) is a GMP-grade methyl donor substrate specifically developed for mRNA enzymatic capping and nucleic acid drug manufacturing applications. Manufactured in a GMP-compliant production environment with a fully animal origin-free process, this product ensures high quality, batch consistency, and reliable performance for mRNA development and commercial production.

As an essential methyl group donor, SAM plays a critical role in enzymatic mRNA capping reactions, supporting the efficient formation of 5′ Cap 0 and Cap 1 structures. It helps improve capping efficiency, maintain mRNA structural integrity, and enhance the translation performance of final mRNA products.

S-Adenosylmethionine (SAM) is fully compatible with various commercial capping enzymes and 2′-O-methyltransferases, making it suitable for in vitro transcription (IVT) mRNA capping workflows from preclinical research to large-scale GMP manufacturing.
