摘要: 目的 利用携带有鼻咽组织相对特异性启动子plunc构建的载体建立转基因动物模型。方法 将plunc-EGFP质粒用XhoⅠ酶切线性化,胶回收线性化片段,稀释浓度4 μg/ml。采用显微注射法将外源基因注射入小鼠受精卵细胞内。结果 产13只小鼠。PCR检测基因整合,其中阳性12只,阳性率92.30%;Southern blot检测阳性3只,阳性率23%。结论 鼻咽组织相对特异性启动子plunc可有效地将外源基因整合入小鼠体内。

Abstract: Objective To construct the vector using specific nasopharynx tissue promoter plunc to establish transgeneic mouse model. Methods Plunc-EGFP plasmid was digested with XhoⅠ, the purified linearized DNA fragments were recovered by gel extraction and diluted to the final concentration of 4 μg/ml, before introduced into fertilized one-cell mouse eggs by pronuclear microinjection. Results Thirteen founder mice were obtained, 12 of which were positive for the integrated EGFP gene as detected by PCR, and 3 were positive shown by Southern blotting. Conclusion Specific nasopharynx tissue promoter plunc can effectively induce exogenous gene integration into the mouse genome.
