We are eager to learn of our customers' specific CLIP requirement and to facilitate their research and product development. MiCLIP: Methylation individual-nucleotide-resolution crosslinking and immunoprecipitation is a specialized version of iCLIP designed to determine which RNA nucleotides are methylated by the RNA methyltransferase Nsun2.Ĭreative Diagnostics offers its vast expertise in CLIP to many clients in the pharmaceutical, medical device and biotech industries. ICLIP: Individual-nucleotide resolution CLIP is a refinement of CLIP that allows single-nucleotide resolution of RBP binding sites. PAR-CLIP: Photoactivatable-ribonucleoside-enhanced crosslinking and immunoprecipitation attempts to solve some of the problems of CLIP, namely, efficiency of crosslinking and resolution of RBP binding sites. Because CIMS are reproducible, high sequencing depths allow CIMS to be differentiated from technical errors.īesides CLIP-Seq, we also offer following services to meet your research demands. CLIP-seq depends on cross-linking induced mutation sites (CIMS) to localized protein-RNA binding sites. We combine UV cross-linking and immunoprecipitation with high-throughput sequencing to identify binding sites of RNA-binding proteins. Due to the irreversibility of the crosslinks, the next step is digestion with a proteinase.Ĭreative Diagnostics can serve full line of CLIP-Seq service. To remedy this, we here conduct temporal-iCLIP (tiCLIP), combining RNAPII transcriptional synchronisation with UV cross-linking of RNA-protein complexes at serial timepoints. The RNA-RBP complexes are then immunoprecipitated. Our data show that the archaeal exosome interacts with mRNAs, housekeeping non-coding RNAs, antisense and circular RNAs, and with posttranscriptionally added RNA tails. For these reasons, UV has become the standard in RNA research. In this study, the iCLIP (individual-nucleotide resolution UV crosslinking and immunoprecipitation) method was used to detect RNAs bound to the archaeal exosome in. Further, UV crosslinks do not form between two proteins. UV crosslinks are also more specific and only link proteins to RNAs that are in very close proximity. Unlike DNA-protein crosslinking which is done with formaldehyde, CLIP uses ultraviolet (UV) light and the crosslinking is irreversible. Cross-Linking and Immunoprecipitation (CLIP)Ĭross-Linking and Immunoprecipitation (CLIP) is an antibody-based technique used to study RNA-protein interactions related to RNA immunoprecipitation (RIP), but differs from RIP in the use of UV radiation to cross-link RNA and the binding proteins.
