Are supermeres a distinct nanoparticle?

Abstract

Abstract We have recently reported the discovery of a new distinct nanoparticle by ultracentrifugation of the supernatant of exomeres at 376,000 x g for 16 hours. We termed the resulting pellet, supermeres (supernatant of exomeres). The Witwer team raised the legitimate question that these two membraneless nanoparticles may arise from a continuous population of extracellular particles. We have reviewed our data here and present additional analyses that reinforce supermeres as distinct nanoparticles.
