产品信息
细胞培养常替代活体生物用于分析基因表达或治疗反应。传统上,人们通过柱提法或化学试剂法从处理过的细胞中提取和纯化 RNA。Luna Cell Ready 裂解模块无需进行传统的 RNA 提取步骤即可评估 RNA 表达水平,是一种快速、方便且灵敏的替代方案。此模块可同时进行细胞裂解、RNA 释放、基因组 DNA 去除,生成的细胞裂解物可直接使用 Luna 通用一步法 RT-qPCR 试剂盒进行 RT-qPCR 分析。与其它 Luna 产品一样,裂解缓冲液包含惰性蓝色示踪染料,使得整个流程可视化。
兼容 Luna Cell Ready 裂解模块的细胞系如下表所示。这些细胞进行 5 个 10 倍梯度稀释(在 50 µl 体系中裂解 10 – 100,000 个细胞),并取 1 µl 裂解物在 20 µl 体系中进行一步法 RT-qPCR 反应。每个细胞系的线性结果区域显示在最后一列。此外,上述裂解模块经测试也可用于一些昆虫细胞系。
