title: Nuclear fraction enriched in interchromatin granules.
abstract: A fraction enriched in interchromatin granules (IG) has been obtained from isolated liver nuclei by digestion with DNase I and extraction with salt solutions. The fraction contains interchromatin granules in the form of conglomerations and some contaminating material of nucleolar and nuclear matrix origin. The ultrastructure of the fraction enriched in IG and electrophoretic patterns of proteins are described.
