商品介绍

Product Introduction

Bioactivity

名称Fluc mRNA
描述Firefly Luciferase 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.
体外活性在HEK293T细胞中,LNPs递送的Firefly luciferase mRNA(0.1 μg )翻译水平略高于阳离子聚合物/脂质或脂质载体递送的情况。而在树突状细胞DCs中,LNPs配制mRNA(0.1 μg )的荧光素酶水平低于市售试剂[1]。
体内活性在 BALB/c 小鼠中注射三种Fluc mRNA-LNPs (1 μg,肌肉注射,单剂量) 24 小时后进行活体成像,显示SM-102 LNP的荧光素酶蛋白表达水平比 ALC-0315 和 cKK-E12 高 60%[2]。Fluc mRNA-LNP(10-20 μg,肌肉注射)可诱导成年 Balb/c 雄性小鼠下丘脑中 Aif1 的短暂激活,但效应具有时间依赖性和脑区特异性[3]。
