the immunochemical localization of hamster liver nucleolar antigens in subcellular fractions ( nuclei , 10,000 x g pellet , 100,000 x g pellet and supernatant ) , nuclear substructures ( chromatin , nuclear matrix , nuclear envelope , nucleoli , rnp particles and nucleosomes ) , and three classes of nonhistone chromosomal proteins with different affinities to dna ( nhcp1 , nhcp2 and nhcp3 ) from nuclease-sensitive and nuclease-resistant chromatin fractions of hamster liver were studied .
