N1-Methyl-Pseudo-UTP, GMP Grade, AOF

Use this modified UTP for the synthesis of mRNA for therapeutics or vaccines. It is designed to meet the specific needs of the pharmaceutical industry (fit-for-purpose):

animal-origin-free (AOF)

ß-Lactam-antibiotic free

extended testing for impurities

manufactured under GMP

Application

This modified UTP can replace UTP in in-vitro-transcription reactions, e.g. for manufacturing mRNA therapeutics and vaccines. This RNA modification provides enhanced protein expression and reduced unwanted immunogenicity against the mRNA molecule itself. Its efficacy has been proven by its use in COVID-19 vaccines.
