摘要: 构建了新霉素抗性基因为筛选标记的带有凋亡抑制基因p35的重组质粒p35IE1Neo, 转化Sf9细胞后, 经G418筛选得到含有p35IE1Neo的Sf9细胞, 克隆化培养后命名为Sf9-35。PCR检测表明, Sf9-35细胞的染色体DNA上有p35基因的扩增带。经放线菌素D处理后的细胞核酸电泳和TdT介导bio-DUTP缺口末端标记(TUNEL)试剂盒检测, 证实Sf9-35具有抗凋亡特性。

Abstract: Transfer vector p35IE1Neo containing anti-apoptotic p35 gene and neomycinresistant gene(as selection marker) was constructed. After transfecting Sf9 cells and G418 screening, cells transformed with p35IE1Neo were obtained. One clone was picked and named Sf9-35. By PCR detection, it was found that the genome of Sf9-35 cells contain p35 gene. After actinomycin D treatment and cellular DNA electrophoresis and detection of TUNEL(TdT mediated bio-dUTP nick endlabeling), Sf9-35 cells were found to be resistant to apoptosis induced by actinomycin D.

Key words: anti-apoptosis, insect cells, p35 gene
