dsRNA: an unwanted byproduct from mRNA IVT mRNA

dsRNA: an unwanted byproduct from mRNA IVT

In vitro transcription (IVT) remains the predominant method for large-scale mRNA synthesis due to its efficiency and scalability. However, a significant challenge associated with IVT is the residual double-stranded RNA (dsRNA) produced as a by-product. This dsRNA can activate innate immune signaling pathways through receptors like RIG-1, MDA5, and others, potentially leading to adverse immune

Why Co-Transcriptional Capping mRNA

Why Co-Transcriptional Capping

In-vitro transcription (IVT) is a reactor-based scheme to manufacture RNA where cell-derived impurities or adventitious contaminants can be avoided thus making the manufacturing process GMP-friendly. The IVT reaction is often carried out at 37°C for 2 hours. During the IVT reaction, T7 or SP6 RNA polymerase binds to the promoter region of a DNA template and catalyzes the
