摘要 目的:构建脂氧素A4受体样蛋白(LRLP)基因的真核表达载体,克隆后转染Hela细胞,观察LRLP基因在Hela细胞中的表达。方法:应用PCR方法,以小鼠睾丸cDNA为模板,扩增出LRLP基因片段,插入质粒pGEM-T中,转化入大肠杆菌JM109。扩增阳性重组质粒,经酶切后纯化并测序鉴定目的片段。构建含绿色荧光蛋白基因的真核表达载体pEGFP/LRLP,转化入大肠杆菌JM109扩增,酶切后再测序鉴定目的片段,抽提质粒后瞬时转染Hela细胞,置激光共聚焦显微镜下照像。结果:测序鉴定表明,克隆的LRLP序列与GenBank中LRLP原序列100%符合,激光共聚焦显微镜下见Hela细胞中LRLP基因表达。结论:成功地构建了真核表达载体pEGFP/LRLP,并转染了Hela细胞。
