Methods In this study,a plasmid vector,rAd5,and rAAV2 were used to transfect rat cochlear marginal cells of stria vascularis by injection into the perilymph through the round window membrane,and the transfection efficiency, target tissue accessibility, cell/ tissue toxicity, time course of expression, and effect on hearing were evaluated in vivo and in vitro.
结果三种载体对原代培养的大鼠耳边缘细胞的转染研究发现,腺病毒的转染效率最高,而腺相关病毒转染对细胞活性影响最小。rAAV2和rAd5对大鼠耳蜗组织的感染实验发现,腺病毒和腺相关病毒携带的增强型绿色荧光蛋白可在多种耳蜗组织中及转染对侧耳蜗组织表达,且并不引起明显的耳蜗组织细胞凋亡。rAAV2携带的EGFP基因在第90天时仍可检测到大量表达。rAd5携带的EGFP基因在第30天时表达明显减弱。

In this paper the thymus DNA of calf and the pBs plasmid are the main objects of our studies in ultraweak luminescence. By means of PIAS(Photon-counting image acquisition), ultraweak luminescence detector and Lambda Bio 40 of UV/VIS spectrophotometer, we studied the UL of DNA induced by the three oxygen free radicals: singlet oxygen Oa, hydroxy radical and superoxide anion(O2 ). We found that the OH can greatly increase the UL intensity of DNA.
本论文以小牛胸腺DNA和质粒pBs为实验材料,利用光子图像探测系统(Photon-counting image acquistion,PIAS)、微弱发光测量仪和UV/VIS分光光度计和生物统计学的成组比较法原理对单线态氧(~1O_2)、羟自由基、超氧阴离子(O_2~-)三种氧自由基诱导DNA超弱发光的变化过程进行了研究,结果发现这三种氧自由基中·OH能诱导DNA的超弱发光发生显著的增强变化,而其他两种氧自由基对DNA的超弱发光并无显著诱导作用。

Total RNA was isolated from cultured human pigmental cells and mRNA was reversly transcribed into cDNA. Then PCR was used to amplify the TRP -2 coding region. The PCR product was cloned into pUC19 plasmid and sequenced, then subcloned into vector pGEX-4T-1. The TRP-2 protein was expressed hi E coli of DH5 a as fusion protein with glutathioneS-transferase induced by IPTG. The fusion protein was purified by glutathione resin column.
我们通过RT—PCR的方法扩增TRP—2编码基因,克隆至pUC19载体并测序,再亚克隆至GST融合表达载体pGEX—4T—1,转化大肠杆菌,IPTG诱导表达了GST/TRP—2融合蛋白,并分析鉴定表达蛋白的可溶性,最后第四军医大学硕士学位论文一用谷氨酚胺树脂柱纯化表达的蛋白。
