A detailed understanding of post-transcriptional gene expression is necessary to correlate the different elements involved in the many levels of RNA–protein interactions that are needed to coordinate the cellular biomolecular machinery. The profile of mRNA, a major component of this machinery, can be examined after isolation from specific RNA-binding proteins (RBPs). RIP-Chip orribonomicprofiling is a versatilein vivotechnique that has been widely used to study post-transcriptional gene regulation and the localization of mRNA. Here we elaborately detail the methodology for mRNA isolation usingRBPimmunoprecipitation (RIP) as a primary approach. Specific antibodies are used to target RBPs, which are then used to capture the associated mRNA.
