Abstract/OtherAbstract:
From rat-liver and ascites-hepatoma chromatins, NaCl-soluble fractions were prepared. The 0.35 M NaCl-soluble fraction from the hepatoma (AH) chromatin contained much non-histone protein of high-molecular weight, compared with the fraction from the rat-liver (RL) chromatin. The 0.35 M NaCl-insoluble, but 2 M NaCl/5 M urea-soluble fraction was composed mainly of 5 classes of histones. These histones were quantitatively not different between AH and RL chromatins. However, H1 histone was rather protease-resistant in AH chromatin, but not in RL chromatin. The proteolytic capacity was also lower in AH chromatin. In addition, in the micrococcal-nuclease digest of AH nuclei, the oligonucleosomes were considerably retained even by long-time digestion, but not in that of RL nuclei.
