    Capping<\/h4>\r\n\r\n\r\n\r\n

    By adding a cap structure to the 5\u2032 end of mRNA molecules, resistance to degradation by exonucleases is greatly improved, resulting in significantly enhanced stability and translation efficiency within cells. The enzymatic method offers high flexibility, and CleanCap\u00ae achieves high purity and high capping efficiency in a single step.<\/p>\r\n<\/div>\r\n<\/div>\r\n\r\n\r\n\r\n

    Modified nucleic acid<\/h4>\r\n\r\n\r\n\r\n

    By chemically modifying bases such as uridine, immune induction by pattern recognition receptors (TLRs, etc.) is suppressed, minimizing inflammatory responses. In particular, UTP modification reduces immunogenicity without compromising translation efficiency and improves the sustainability of protein expression.<\/p>\r\n\r\n\r\n\r\n

    UTR optimization<\/h4>\r\n\r\n\r\n\r\n

    By optimizing the sequence and secondary structure of the 5'- and 3'-untranslated regions (UTRs), ribosome binding and recycling efficiency are improved, thereby extending mRNA stability and translation duration. Proper placement of stabilization signals and RNA-binding protein recognition sites is key.<\/p>\r\n\r\n\r\n\r\n

    Codon optimization<\/h4>\r\n\r\n\r\n\r\n

    By replacing codons in the amino acid sequence of the target protein with those that are frequently used in the host cell, the translation speed of the ribosome is increased, maximizing protein production. GC content and secondary structure are also taken into consideration to achieve both translation efficiency and mRNA stability.<\/p>\r\n<\/div>\r\n<\/div>\r\n\r\n\r\n\r\n
