Detection of Satellite DNA by density gradient ultracentrifugation
    In an ultracentrifuge experiment, the bulk of nuclear DNA has a characteristic [G+C] content, which gives it a characteristic range of density that corresponds to the main band (MB) in a cesium chloride (CsCl) density gradient. The presence of repetitive DNA with a distinctive [G+C] content was first detected by smaller "satellite" bands with a lower density.
