operating density is kept within the 2.5 – 2.7 g/cm3 range within the De Beers Group operations, this is easily achievable with the milled FeSi grade used5. Operating at high densities would result in the viscosity of the medium increasing thereby leading to poor separation. Operating at lower densities might lead to the medium being

Consequently, Meselson and Stahl struggled to see clear locations within the density gradient with the highest concentration of bacterial DNA. Therefore, in September 1957, Meselson and Stahl switched to using the DNA from the bacteria Escherichia coli (E. coli). E. coli DNA formed clearer concentration peaks during density …
Density gradient ultracentrifugation is currently considered the gold-standard method for achieving the highest-purity exosome samples, as they remove non-specifically bound proteins from vesicles ( Fig. 2) [28]. As such, density gradient ultracentrifugation is commonly used to isolate exosomes for exosomal proteomics and RNA sequencing …
