Mouse satellite DNA isolated by Ag+ -- CsSO4 density gradients contains G+C rich, slow reassociating sequences

E Ullu et al. Biochem Exp Biol. 1977.

Abstract

Mouse satellite DNA sequences isolated by centrifugation in CS2SO4--Ag+ gradients are analyzed for buoyant density by CSCl density gradients and for their content of fast reassociating sequences by denaturation and partial reassociation. Our data suggest that in CS2SO4 gradients silver ions separate a satellite band which contains both fast reassociating G+C rich sequences and slow reassociating, A+T rich DNA sequences.
