IntegrateRNA is an outstanding biotechnology company with years of experience in RNA-protein interaction analysis. We offer customized circRNA pull-down assay service to help you validate the interaction of circRNA-miRNA and circRNA-RBP. We always work together with you to solve specific challenges and chase highest-level customer satisfaction. Circular RNA (circRNA) is recently discovered as a special novel type of endogenous noncoding RNA (ncRNA), and attracts considerable attention due to its powerful functions and unique properties. It’s reported that some circRNAs contain several miRNA binding sites and act as a sponge to impact the bio-function of miRNA. In addition, circRNA can serve as a protein decoy which harbors binding sites for a single or multiple proteins and regulate gene expression. Thus, the interaction analysis of circRNA-miRNA and circRNA-RBP is crucial to reveal the biological function and mechanism of circRNA. RNA pull-down is an in vitro technique for detection of protein-RNA interactions using labeled RNA as bait. Currently, biotinylated probes based on back-splicing junction sequence are widely applied to circRNA pull-down assay. However, due to the probe sequence overlap with the often more abundant linear host RNA, it is difficult to completely exclude the interference of the host linear RNA. IntegrateRNA introduces the up-to-date circRNA pull-down technique to help you identify the interaction between miRNA/RBP and circRNA.
