Abstract
This method is for the immunoprecipitation of Flag-Tagged RNA binding proteins from mammalian cell lines and isolation of the bound RNAs for analysis by quantitative real-time PCR. The RNA binding protein of interest should be tagged with the M2 Flag-tag and expressed in the mammalian cell line of interest (Knuckles et al., 2012). However, specific antibodies for the protein of interest can be used in conjunction with Sepharose G-beads.
