Popis: Liquid-liquid phase separation (LLPS) has been known to drive formation of biomolecular compartments, which can encapsulate RNA and proteins among other cosolutes. Such compartments, which lack lipid membrane, have been implicated in origins of life scenarios as they can easily uptake and concentrate biomolecules, similar to protein-based intracellular condensates. Indeed, chemical interactions that drive LLPS in vitro have also been shown to form similar sub-cellular compartments in vivo. Here we describe methods to prepare compartments formed by complex coacervates, which are formed by LLPS of oppositely-charged polyions, and to probe the structures and functions of RNAs in them. These methods can be adapted to study RNA biochemistry in compartments formed by diverse artificial and biological macromolecules.
