RNA–DNA hybridsS9.6 antibodySpike-inqDRIP (quantitative DNA–RNA immunoprecipitation)R-loops are three-stranded nucleic acid structures, comprising an RNA-DNA hybrid and a displaced strand of ssDNA. R-loops have important physiological roles in cells, but deregulation of R-loop dynamics can also ...
基于抗体的DNA修饰位点鉴定是一种传统的,被广泛应用的较为简单的方法。目前5mC、5hmC、5fC、5caC均有商业化的抗体,可用于做DNA IP(DNA immunoprecipitation, DIP)。利用5hmC-DIP可鉴定癌症患者血液中循环DNA的5hmC【22】,说明此方法灵敏度高,无须耗费大量DNA,具有临床应用的潜力。但是DIP无法提供单碱基精度的...
5. Chromatin Immunoprecipitation(染色质免疫沉淀) 染色质免疫沉淀(ChIP)是一种基于抗体与特定蛋白质结合的技术,可以捕获与该蛋白质结合的染色质。ChIP-seq是一种基于ChIP的技术,通过使抗体附着在特定蛋白质上,捕获与其结合的DNA片段。通过这种方法,可以确定特定蛋白质与染色质结合的位置和强度,从而揭示DNA-RNA相互作用...

5. Ago HITS-CLIP (high-throughput sequencing of RNAs isolated by crosslinking immunoprecipitation) 前面已经提到miRNA可以与mRNA结合调控基因的表达,有研究指出miRNA仅需要6-8nt与mRNA精确配对即可发挥作用。但这对利用碱基组成重头预测靶标 mRNA是一个巨大的挑战。miRNA与Argonaute蛋白复合物构成RISC核心元件,并引导...
They observe such hybrids by developing a purification method named cytoplasmic DNA–RNA hybrid immunoprecipitation (cytoDRIP). Notably, the formation of cytoRDHs depends on both the endonuclease XPG, which is known to process nuclear R-loops, and exportin-1, which actively exports nucleic acids to...
