5-Methoxy-UTP
5-Methoxy-UTP is an analogue of the naturally occurring uridine triphosphate (UTP). Similar to N1-methylpseudouridine and pseudouridine modifications, 5-methoxyuridine is another common chemical modification used for in vitro mRNA synthesis in order to improve mRNA activity and reduce innate immune responses. Chemical modifications of mRNAs with 5-methoxyuridine, N1-methylpseudouridine and pseudouridine have been shown to significantly improve the expression of enhanced green fluorescent protein (eGFP) in a variety of cell lines, among which 5-methoxyuridine-modified eGFP mRNA is more stable than other eGFP mRNAs. In addition, replacing UTP with 5-methoxy-UTP in Cas9 mRNA has also been reported to reduce innate immune responses, making the broad use of Cas9 possible both in vitro and in vivo.
