RIP: an mRNA localization technique.

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 or ribonomic profiling is a versatilein vivo technique 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 using RBP immunoprecipitation (RIP) as a primary approach. Specific antibodies are used to target RBPs, which are then used to capture the associated mRNA.
