从1～2个T75培养皿的感染细胞培养液中纯化腺病毒
产品简介
本系列试剂盒可快速，高效地从腺病毒感染的细胞培养液中分离纯化腺病毒，相比于传统CsCl超速离心的腺病毒病毒纯化方式（需要24个小时才能完成纯化），本试剂盒可以在1个小时内完成病毒纯化，操作简单，快速，纯化率高，纯化到的病毒颗粒可直接用于下游实验，如细胞和动物感染。
产品特点
?操作简单，快速，可以在1个小时内完成病毒纯化，不依赖于超速离心操作。
?纯化效率高：小量纯化，可从1~2个T75瓶培养的细胞培养液中纯化病毒颗粒高达1x1012VPs
?每个纯化柱，可以重复利用一次，用于纯化相同种类的腺病毒。
保存条件
纯化柱和脱盐柱保存于4℃，其它组分室温保存。

病毒液通过pre-filterdisc的时候是不是要制造一个真空环境产生压力差使液体通过？这个时候是用自备的针管还是试剂盒配的5毫升的针管啊？
试剂里面含有的是病毒的抗原，现在基本都是人工合成或提取的，跟病毒完全是两回事
