In Vitro Transcription For mRNA Production

In vitro transcription (IVT) is a foundational step in producing mRNA vaccines and therapeutics, relying on a precisely orchestrated reaction environment to achieve high-quality output. At the core of the process, T7 RNA polymerase drives mRNA synthesis by incorporating nucleoside triphosphates (NTPs) into the growing transcript. The reaction’s efficiency and fidelity depend on more than the enzyme and template alone—optimized buffer systems, salts, and key additives such as inorganic pyrophosphatase, dithiothreitol, spermidine, and RNase inhibitors help boost transcription performance, limit byproduct formation, and protect the mRNA from degradation. With carefully controlled raw materials designed for pharmaceutical use, IVT workflows gain the consistency and reliability needed for scalable mRNA manufacturing.
