The Ribopuromycylation (RPM) technology, developed by Dr. Jon Yewdell and Dr. Alexandre David, offers a powerful and universal method for visualizing and studying protein translation within cells. RPM involves the use of puromycin, a molecule that mimics a tyrosyl-tRNA and terminates translation by becoming covalently incorporated into the nascent protein chain's C-terminus within the ribosome's A site. This technique enables the immobilization of puromycylated nascent protein chains on ribosomes when chain elongation inhibitors like cycloheximide or emetine are utilized. Anti-puromycin monoclonal antibodies (mAbs) are then employed to localize actively translating ribosomes through immunofluorescence analysis of fixed and permeabilized cells or tissues. RPM has revolutionized the study of protein translation, providing researchers with a straightforward and versatile tool to investigate this fundamental cellular process in various biological contexts.
