tdTomato-mRNA is an mRNA molecule capped at the 5' end, polyadenylated at the 3' end, and modified with N1-Me-Pseudo UTP, mimicking the processed mature mRNA found in eukaryotes. The mRNA is capped co-transcriptionally using 3'-O-Me-GAG, forming a Cap1 structure which enhances mRNA stability and translation efficiency. The incorporation of the modified nucleotide N1-Me-Pseudo UTP reduces innate immune stimulation and increases mRNA stability. The addition of the poly(A) tail further stabilizes the mRNA and enhances its translation initiation efficiency.

In vitro | Fluorescence detection was performed 24 hours after transfecting HeLa cells with tdTomato mRNA (100 ng), and obvious red fluorescent signals were observed[1]. |
In vivo | tdTomato mRNA LNP-1 was injected intravenously into wild-type C57BL/6 mice at a dose of 0.3 mg/kg, and no tdTomato fluorescence was observed in the liver, spleen, or lungs after 24 hours, indicating that an alternative method for measuring mRNA translation in whole organs is necessary for LNP-1.[1]. |
