目的:构建小鼠髓样相关蛋白14(MRP14)的真核表达载体,观察其在NIH3T3细胞中的表达定位情况。方法:提取BALB/c小鼠肝脏组织的总RNA,通过逆转录-聚合酶链反应(RT-PCR)扩增得到MRP14编码序列。然后将该编码序列克隆到带有血凝素(HA)标记的载体pcDNA3-HA上,随后转染NIH3T3细胞,在荧光显微镜下观察结果。结果:重组质粒经聚合酶链反应(PCR)、酶切和测序鉴定证明构建正确。转染实验发现,该质粒能够在NIH3T3细胞中表达,表达产物主要定位在细胞质中。结论:成功构建带HA标签的MRP14真核表达载体。该载体能在哺乳动物细胞中有效表达并正确定位,为下一步深入研究MRP14作用细胞的信号通路提供了一个重要工具。
Objective:To construct eukaryotic expression vector of myeloid-related protein-14(MRP14)for the detection of the expression and localization in NIH3T3 cells.Methods:Total RNA from the liver of BALB/c mice was extracted using a routine method.The coding sequence of mouse MRP14 (GenBank accession No. NM_009114.2)was amplified by reverse transcription-polymerase chain reaction(RT-PCR)and cloned into he- magglutinin(HA)-tagged mammalian cell expression vector pcDNA3-HA,and it was followed by transfection in NIH...
