    "abstract": "We report that the properties of the isotropic to nematic liquid crystalline\nphase transition of F-actin depend critically on the average filament length.\nFor average filament lengths longer than 2 $\\mu$m, we confirm previous findings\nthat the phase transition is continuous in both alignment and concentration.\nFor average filament lengths shorter than 2 $\\mu$m, we show for the first time\na first order transition with a clear discontinuity in both alignment and\nconcentration. Tactoidal droplets of coexisting isotropic and nematic phases,\ndiffering in concentration by approximately 30%, form over the course of hours\nand appear to settle into near equilibrium metastable states.",
