新普京888.3app新升级lncRNA慢病毒包装系统与传统包装的方式比较如下：

新普京888.3app慢病毒系列产品：

定制病毒：涵盖过表达/干扰、CRISPR/Cas9、Cumate诱导表达系统、Tet-on/off系统、Cre-loxp系统。

现货慢病毒：涵盖CRISPR/Cas9敲除或激活文库、自噬单标或双标、荧光素酶现货、Cre/Flp重组酶、光遗传学等工具类现货。


慢病毒感染效果图：

慢病毒能够有效地感染培养的肝细胞、心肌细胞、神经元、内皮细胞、干细胞等多种类型的细胞。



不同培养体系对应细胞数、感染试剂用量及病毒量参考：



储存液浓度：Polybrene：1ug/μl，Polybrene-plus：100ug/μl

参考工作浓度：Polybrene：5μg/ml，Polybrene-plus：1μg/μl

※细胞数量为推荐铺板细胞数量，需根据细胞大小调整铺板数量（以感染时细胞密度30%为宜），按照实际感染时细胞数量去计算病毒加入量。

※为增加病毒与细胞接触的几率，可适当减少感染时培养基的体积。

感染复数（Multiplicity of Infection, MOI），含义为感染时病毒和细胞数量的比值，即平均每个细胞感染的病毒活性单位数（慢病毒单位为TU/cell）。


实验中按照设置好的MOI计算每孔需要加入的病毒量：
每孔加病毒量(μl)=MOI×感染时的细胞数/滴度(TU/ml)×1000。
