  • Title: Changes in size and shape of chromatin particles after successive removal of histones.
    Author: Kaliński A, Toczko K.
    Journal: Acta Biochim Pol; 1976; 23(2-3):103-8. PubMed ID: 970029.
    Abstract:
    The preparations of whole chromatin, chromatin selectively depleted of histone f1, depleted of all lysine-rich histones (f1, f2b, f2a2), and DNA was studied by viscosimetric and light scattering methods. The obtained results were used for calculation of the dimensions and packing ratios of DNA for the preparations studied. The packing ratio in whole chromatin is 7.2 and is almost unaffected by selective removal of histone f1 (6.9), but decreases on successive removal of the remaining four histones, the decrease being dependent more on the quantity than the kind of the dissociated histones.
