Fluc-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 that 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 improves its translation initiation efficiency.

In vitro | In HEK293T cells, LNP-delivered mRNA (0.1 ug) showed slightly higher translation levels than mRNA delivered via cationic polymer or lipid. Conversely, DCs exhibited lower luciferase levels with LNP-formulated mRNA compared to commercial reagents[1]. |
In vivo | Intramuscular injection of three Fluc mRNA-LNPs (1 μg, single dose) into BALB/c mice, followed by in vivo imaging 24 hours post-injection, revealed that SM-102 LNP mediated a 60% higher luciferase protein expression level compared to ALC-0315 and cKK-E12 [2]. Fluc mRNA-LNP (10-20 μg, intramuscular injection) can induce transient activation of Aif1 in the hypothalamus of adult male Balb/c mice, although this effect shows temporal dependence and brain region specificity[3]. |
