Detection of Satellite DNA by gradient ultracentrifugation
    The bulk of nuclear DNA has a characteristic [G+C] content, which gives it a particular density, corresponding to the main band (MB) in a cesium chloride (CsCl) gradient. The presence of repetitive DNA with a distinctive [G+C] content is indicated in a centrifugation experiment is by a smaller "satellite" band with a lower density.
