Abstract

The sialic acid-containing glycosphingolipids known as gangliosides can reverse the heat stabilization of DNA by histones. The ability of pure mono-and disialogangliosides to dissociate reconstituted nucleohistone is directly dependent on their sialic acid content; they are effective in concenitrations above their critical micelle concentration.
