Raw data and plotting script for a submitted manuscript titled "Active Transport as a Mechanism of Microphase Selection in Biomolecular Condensates". In this work, we introduce a physical mechanism by which motor-driven transport along cytoskeletal filaments can arrest coarsening in phase-separating biomolecular condensates. Using analytical theory and three-dimensional numerical simulations, we show that stochastic binding and release of proteins to rapidly moving motors generates an effective long-range repulsion, shifting the spinodal and stabilizing finite-sized droplets at a tunable length scale.
