实验原理：

TRAP方法首先设计GST-MS2融合表达载体和ncRNA-MS2茎环结构串联重复载体，共转细胞获得GST-MS2融合蛋白和ncRNA-MS2融合RNA，在胞内形成GST-MS2~ncRNA-MS2与蛋白或RNA的复合体；然后裂解细胞，利用谷胱甘肽亲和琼脂糖磁珠拉取获得目的蛋白-RNA复合物；最后进一步分离纯化，获得目的蛋白或目的RNA进行下一步检测分析。

 

产品优势：

1. 伯信独立研发。

2. 解决了传统的TRAP实验目前只应用于LncRNA等互作RNA或蛋白研究的局限性问题。

3. 使用环状RNA表达载体而非探针进行杂交，避免了circRNA研究中接头序列被蛋白结合后探针不能结合circRNA导致的假阴性影响，且降低了探针杂交过程中RNA的降解。
