In recent years, the outbreak of nd appear some new characters, it is reported that the amount of immunity defeat on nd increased, even chicks with high hi titer can be infected by ndv virulent strain. the gene - engineering vaccine is badly needed to control nd outbreak. so newcastle disease virus strain b95, a naturally avirulent and heat stable strain, was introduced from australia
新城疫是國際獸疫局公布的16種烈性傳染病之一。近年來，新城疫的爆發出現了許多新特點，免疫失敗報道增多，甚至抗體水平較高的雞群也發病。為控制新城疫的爆發，急需研製基因工程苗。 -
Results we construct recombinant angiostatin baculovirus with a high virus titer ( 2 + 108 pfu / ml ) successfully. recombinant angiostatin was effectively expressed in insect cells ( sf9 ) as 53 kd fusing protein and its expression level was about 90 % of insect cellular total soluble proteins. the recombinant angiostatin protein could inhibit endothelial cell proliferation in vitro with ic50 value of 2
實驗結果我們成功地構建了滴度高達2x10 『 pm llil的angiostatin重組? 2 ?桿狀病毒，並在昆蟲細胞sffi中高效表達了分子量為53kd的an giostatin重組蛋白，重組angiostatin蛋白不僅在體外顯著抑制內皮細胞的生長， k 。 -
Once the recombinant virus has been i - dentified, we amplified the p - 1 stock to attain the large scale, high - titer viral stock in order to initiate expression studies. the recombinant angiostatin was produced from spodoptera frugiperda 9 ( sf9 ) insect cells infected by the high titer virus stock we have prepared. the time course for expression of recombinant protein was detected by sds - page and western blot, which can determine the optimal multiplicity of infection ( moi ) and the appropriate time of harvest for the protein
表達重組蛋白angiostatin ：用制備好的帶有矗s標記的融合性angiostatin基因的高滴度重組桿狀病毒貯存液感染草地貪夜蛾sfg細胞，用sds page電泳和hsternblot對感染不同時間後分泌的重組蛋白做時間表達分析，依此確定最適的感染復數（ moi ）和感染時間，以達到重組蛋白表達水平最適化，而後大規模進行重組蛋白的表達， sds page用來分析重組蛋白， westernblot用來在蛋白表達水平低的情況下檢測表達的特異重組蛋白。 -
Moreover, local lesion assay on chenopodium amaranticole showed that the virus titer in the transgenic tomato plants were significantly lower than that of the non - transgenic plants. the collective results demonstrate that ttom1 is a host factor involved in the replication and / or maintenance of cmv in tomato
結果表明，轉反義ttom1番茄植株產生的枯斑數比非轉基因番茄植株的枯斑數顯著減少，表明轉基因番茄中cmv的濃度要明顯低於非轉基因對照植株，證明番茄ttom1基因是與cmv的復制效率有關的一個寄主因子。 -
12 - day - old spf chicken embryo was inoculated with various concentration of aiv ( h5 subtype ). then allantoidal fluid was collected and virus titer was measured
將禽流感病毒（ h5n1 ）接種12日齡spf雞胚，所得尿囊液濃縮后，一步法提取病毒rna 。
