Physicochemical properties of salt-soluble, unsheared chromatin. The mass per unit length by light scattering.

L Karawajew, H Fenske, M Böttger, R Lindigkeit.   

Abstract

The mass per unit length of 7 X 10(3) (formula: see text) and the corresponding DNA packing ratio of about 14 for the chromatin soluble at moderate ionic strengths has been determined by light scattering. With the increase in ionic strength and corresponding release of histone H1 the DNA packing ratio has been found to decrease down to 4.4. The data obtained are consistent with the idea suggested previously that the salt-soluble chromatin is organized in double nucleosome chains arranged side-by-side and stabilized by H1. With salt-induced H1 release the double chain dissociates and the nucleosomal DNA partially unravels.
