Purification of Noncoding RNA and Bound Proteins Using FLAG Peptide-Conjugated Antisense-Oligonucleotides

To understand the function of certain RNAs, including noncoding RNAs, it is important to identify the proteins that interact with the RNAs. Here we describe the method for purification of ribonucleoprotein (RNP) complexes composed of specific cellular RNAs by pull-down with FLAG peptide-conjugated antisense oligonucleotide (ASO). Using this method, we identified a novel protein component of U7 snRNP complex.
