采用6孔板接毒后,铺上低溶解度琼脂糖,第二天就出来了这些病变,正常细胞没有出现这种现象。
按说空斑应该出现多个,但我的六孔板中一个空最多也就出现了2个空斑,也不像文献报道的那样规则,而且很大!
由于没有做梯度稀释,会不会是接毒量过大造成的啊?请大侠指点,万分感谢!
2) 克隆技术使用使倾向于量繁殖现种群利用价值体,按自规律促进整种群优胜劣汰.意义说,克隆技术干扰自进化程.
3) 克隆技术种昂贵技术,需要量金钱物专业士参与,失败率非高.莉277实验唯.虽现发展更先进技术,功率能达2-3%.
4) 转基物提高疾病传染风险.例,产药物牛奶牛染病毒,种病毒能通牛奶染病
5) 克隆技术应用于体导致代遗传性状工控制.克隆技术引起争论核能否允许发育初期类胚胎进行遗传操作.伦理家所能接受.

1.如果在引物的5’引物引入了T7启动子,3‘引物也引入了polyT,PCR扩增出全长片段,回收纯化之后可以用来直接做体外转录么?为什么看到文献里都是先把这个PCR片段连接到载体里面,扩增之后提取出来线性化之后,再进行体外转录。是不是转录对模板的量有要求?
2.如果使用一些带有T7启动子序列的载体比如pBluescriptSK,在启动子序列和酶切位点之间还有多余的一段序列,这段序列也会被启动子转录,这一小段多余的序列是否会对接下来的转染以及病毒拯救带来影响?
3.有人在做反向遗传么,哪些载体可以用来进行体外转录?插入片段为7.5K。
般基克隆物体直接取基包括面几步骤
提取植物或者物基组DNA(试剂盒)————做PCR需要基扩增(顺利2搞定)——扩增基做酶切——基连接想插入载体面(顺利1-2)——鉴定克隆基
步骤都商品化试剂或者试剂盒 要思路清晰做起快 1-2周能完
