Identification of RNA-binding Proteins

This protocol describes the extraction of RNA-binding proteins (RBPs) from cell lysates. In order to pull down target RBPs, 5-bromo-UTP (BrUTP)-incorporated RNA probes are used, which are generated by in vitro transcription. The schematic diagram (Flowchart) with procedure is indicated (Figure1 and Figure 2).Figure 1. Schematic diagram of procedure (A-H). Flow chart of experimental procedure is indicated at A-H.Figure 2. Linearization of plasmids by restricted enzyme. The plasmid is cut at restriction sites adjacent to its cloning element.
