RIP技术(RNA Binding Protein Immunoprecipitation,RNA结合蛋白免疫沉淀),是研究细胞内RNA与蛋白结合情况的技术,是了解转录后调控网络动态过程的有力工具,能帮助我们发现miRNA的调节靶点。RIP这种新兴的技术运用针对目标蛋白的抗体把相应的RNA-蛋白复合物沉淀下来,然后经过分离纯化就可以对结合在复合物上的RNA进行分析。实验流程:1. 用抗体或表位标记物捕获细胞核内或细胞质中内源性的RNA结合蛋白。2. 防止非特异性的RNA的结合。3. 免疫沉淀把RNA结合蛋白及其结合的RNA一起分离出来。4.结合的RNA序列通过microarray(RIP-Chip),定量RT-PCR或高通量测序(RIP-Seq)方法来鉴定。
