Identifying the interactions between long non-coding RNAs (lncRNAs) and proteins is very important to decipher the functional mechanisms of lncRNAs. CD Genomics provides next-generation sequencing (NGS)- and mass spectrometry (MS)-based methods for building in vitro or in vivo lncRNA-protein interaction network and providing vital insight into the functions and action mechanisms of lnRNA. Our solutions for lncRNA-protein interaction analysis include ChIRP-seq, CLIP-seq, RIP-seq, and ChIRP-MS.
Non-coding RNAs with a length of greater than 200 bases are referred to as lncRNAs, which have attracted a lot of attention in recent decades. Many studies have found that lncRNAs play an important role in post-transcriptional gene regulation and chromatin remodeling by targeting chromatin-modifying enzymes to distinct genomic sites. The mutations and malfunctions of lncRNAs are closely associated with a number of human diseases. As lncRNAs interact with various proteins, the prediction of lncRNA-protein interactions is a sufficient way to explore lncRNA functions and. A variety of assays have been developed to build lncRNA-protein interaction network. RNA pull-down assays use either bead-bound proteins or immobilized synthetic RNAs to capture lncRNA-protein interactions. RNA immunoprecipitation (RIP) assays use a protein of interest to capture interacting endogenous RNAs. Both the methods can be applied to material from proliferating and quiescent cells, thus providing insights into how lncRNA-protein interactions are altered between these two cellular states. As both RNA pull-down and RIP assays capture in vitro RNA-protein interactions. We also provide in vivo detection of lncRNA-protein interactions using ChIRP and CLIP, both of which use crosslinking to stabilize the protein-RNA complexes. These assays are further combined with NGS or MS to profile lncRNA-protein interactions and provide detailed insight into the functions and mechanisms of lncRNAs. Our services are devoted to offering accurate and reproducible data to support lncRNA research.
