Ribonucleoprotein immunoprecipitation (RNP-IP): A direct in vivo analysis of microRNA-targets

Academic Article


  • We have developed a novel Ribonucleoprotein Immunoprecipitation (RNP-IP) method to isolate miR-RISC complexes, associated microRNAs and target mRNAs. Our method characterizes mRNAs present in immunoprecipitates containing miR-RISC complexes that were obtained using GW182 and AGO2 antibodies. MicroRNA bound transcripts were reverse transcribed and amplified using seed sequence and 3′UTR derived primers. This flexible IP-based assay is a straightforward method to identify miRs participating in gene regulation and their cognate mRNAs in real time. © 2010 Wiley-Liss, Inc.
