Examples
- Materials : in this study , bone marrow stromal cells ( bmscs ) were used as seed cells of chondrocyte tissue engineering after transfected transforming growth factor ( tgf ) - ft , gene by lipofectamine . then the biological characters of the transfected bmscs were investigated by many methods
本研究以骨髓基质干细胞( bmscs )作为靶细胞， tgf _ 1基因片段作为目的基因，经lipofectamine转染目的基因与靶细胞中，观察bmscs经基因转染后的生物学特性。 - Another 561 bp fragment of the orf of p22 gene was amplified by pcr , and digested by pst1 and xba 1 . the amplified fragment was cloned into pbudcfal to construct the recombinant plasmid pbudce4 . 1 / p22 . then transfected it into the murine macrophages by using lipofectamine , the expression of p22 - mrna in the transfected macrophages was identified by rt - pcr
同时扩增p22编码基因orf的全长561bp片段，经pst 、 xba双酶切后，定向克隆于质粒pbudce4 . 1 ，构建真核重组重组表达质粒pbudce4 . 1 / p22 ，通过脂质体介导转染入小鼠巨噬细胞raw264 . 7 ，以rt - pcr方法鉴定目的基因在巨噬细胞中的表达。 - After the recombinant plasmid pcdna3 . 1 / ts87 was identified by digestion of hindlll and bamh i , it transformed into cos7 by lipofectamine . expression product was identified by immunohistochemical method , sds - page and western - blot . the immunocytochemistry result has shown that specific brown - staining grains were found in the cytoplasm of cells transformed by recombinant plasmid versus not seen in cells transformed by pcdna3 . 1 or normal cells ; the sds - page result has revealed that a band about 3 8kb was found in cell lysis transformed by recombinant plasmid versus not in cells transformed by pcdnas . l or normal cells ; the western - blot result has showed that only the band about 38kd was recognized by sera from rabbit infected by t . s artificially and sera from rabbit immunized with soluble antigen of t . s and with protein expressed by ts87 gene and by a monoclonal antibody of t . s
通过细胞的免疫组化，细胞裂解物的sds - page电泳， westem - blot分析检测目的基因的表达情况。免疫组化结果显示：重组质粒转染的细胞质中有棕褐色颗粒，而空载体转染细胞及正常细胞无此现象；细胞裂解物sds - page电泳结果显示：只有重组质粒转染的细胞在约38kd处有明显的蛋白带，这与理论计算的ts87基因表达蛋白的分子量为38kd基本一致； western - blot分析结果显示：约38kd的蛋白带能够分别被旋毛虫感染兔血清，成虫虫体可溶性抗原免疫兔血清， ts87基因原核表达蛋白免疫兔血清( ts87血清)以及一株具保护性的旋毛虫单抗特异识别。 - In order to study the function of cycling2 in vitro culturing cell line , we used pires - g2 eukaryotic expression vector transfecting human gastric cell line sgc - 7901 and human embryo kidney hek - 293 cells by lipofectamine plus reagent , and studied the function of cycling2 expression on the cell proliferation in vitro , further investigated the regulation mechanism of cycling2 . at the same time , we made a study on the expression level change of cycling2 in normal gastric tissue and different type and different stage of gastric carcinoma tissue . material and method 1 material : piresneo vector was purchased from clonetech , plasmid extraction and purification kit was purchased from qiagen company ; rpmi 1640 , , dmem fetal calf serum were obtained from gibco / brl ; lipofectamine plus and g418 were purchased from life technologies ; ultrasensitive ? s - p kit , mouse monoclonal antibody p21wafl ( in use ) , dab staining kit were purchased from maixin company
