摘要 目的探讨构建具有神经细胞表达特异性的TUBA1α-EGFP真核表达载体,为进一步研究神经元细胞的发生与转化奠定基础。方法采用PCR技术克隆出长分别为1.121 kb与0.72 kb的TUBA1α启动子及EGFP基因部分序列,利用Gateway克隆技术构建pLV.EX2 d.null-TU-BA1α>EGFP质粒。最后对产生的重组子进行琼脂糖凝胶电泳和测序鉴定。结果经琼脂糖凝胶电泳鉴定,所克隆的1.121 kb与0.72 kb的TU-BA1α启动子及EGFP基因片段成功地连接到pLV.Des2 d.null载体上,DNA测序证实插入到载体中的片段为目的片段。结论成功构建了神经细胞特异性真核表达载体TUBA1α-EGFP。
