Size distribution of human urinary particles isolated by ultracentrifugation alone versus ultracentrifugation followed by SEC column-purification. (A–E) Human urine was collected from subjects listed in Table 1. Particle diameter size and concentration determined by nanoparticle tracking analysis for human urinary particles isolated using ultracentrifugation and remained unpurified (UNp) or isolated via ultracentrifugation and then fractionated using SEC column-purification, with fraction 6 (F6), fraction 7 (F7), and fraction 8 (F8) being analyzed. A 500 nm size cutoff was used for data representation. (D) F8 was below the limit of detection.
