Enzyme Based System for Production of Messenger RNA with Increased Transfection Efficiency
Summary
The USPTO published patent application US20260110010A1 on April 23, 2026, filed September 25, 2025, for an enzyme-based system designed to improve the production and transfection efficiency of messenger RNA (mRNA). The application names five inventors: Brett Morimoto, Kayvan Niazi, Annie Shin, Philip T. Liu, and Lise Geissert. The invention relates to methods for producing proteins used in in vitro transcription of mRNA, with evaluation of protein purity and efficacy based on how effectively the resulting mRNA transfects cells and produces encoded proteins.
“A method for the production of proteins used in the in vitro transcription (IVT) of messenger RNA (mRNA), wherein the proteins are evaluated for purity and efficacy by the efficiency with which mRNA synthetically derived therefrom, subsequently transfects cells and produces encoded proteins.”
