The Magna RIP RNA Binding Protein Immunoprecipitation kit (Product ID: RIP; MilliporeSigma) was used for RIP, according to the manufacturer's instructions. MKN45 cell lysates were collected and 100 µl lysate per reaction was incubated with NC IgG (1:500; cat. no. ab172730) or anti-EIF4A3 (1:1,000; cat. no. ab180573) antibody (both Abcam) conjugated to protein A/G magnetic beads (EMD Millipore) at 4°C overnight. Immunoprecipitated RNA was then extracted and detected by RT-qPCR to confirm the enrichment of binding targets.
