| 名称 | eGFP mRNA |
| 描述 | eGFP-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. |
| 体外活性 | eGFP mRNA-LNP(1 μg/mL, 24小时)在HeLa细胞中可以大量翻译成EGFP蛋白,但在巨噬细胞中翻译率却很低[1]。Egfp mRNA-LNP(0.25-1ug/ml,6-48小时)在人类原代肺泡上皮细胞和肺成纤维细胞中表现出剂量和时间依赖性的转染效率。在低剂量(0.25 μg/mL)下,转染效率在24小时后达到最高。在高剂量(1 μg/mL)下,转染效率在24小时和48小时之间几乎相同[2]。 |
| 体内活性 | eGFP mRNA-LNP (2 mg/kg,静脉注射,单剂量) 在注射16 小时后对 C57Bl/6J 小鼠进行活体成像,显示Egfp mRNA仅在肝细胞中被翻译为蛋白质,而在库普弗细胞(KC)中未见明显的翻译信号[1]。 |
