摘要: 为了建立内皮素受体拮抗剂筛选系统,克隆人ETA基因,构建真核表达载体,并实现pTag-Lite SNAP-ETA在CHO-K1细胞中的瞬时表达。从人肺腺癌细胞系A549中克隆人ETA基因,连接到pTag-Lite SNAP质粒,构建表达载体pTag-Lite SNAP-ETA,用FuGENER HD转染试剂将表达载体pTag-Lite SNAP-ETA转染入CHO-K1细胞内,通过荧光显微镜检测融合蛋白SNAP-ETA的表达。DNA测序结果表明pTag-Lite SNAP-ETA表达载体构建成功,荧光显微镜检测结果表明人ETA在CHO-K1细胞中有效表达。

Abstract: It was to facilitate inhibitor screening of endothelin receptor, cloning of human endothelin receptor gene ETA, construction of eukaryotic expression vectors and transient expression of pTag-Lite SNAP-ETA in CHO-K1 cells. Method Human ETA gene fragment were amplified from human lung cancer cell line A549 via RT-PCR and inserted into pTag-Lite SNAP plasmid, the recombinant plasmids were then transiently transfected into CHO-K1 cells using FuGENE? HD, expression of ETA was observed via fluorescence microscope. Result Sequencing result showed pTag-Lite SNAP-ETA expression vector were correctly constructed. Fluorescence microscope images indicated that two vectors were expressed in CHO-K1 cells.
