Chromatin very small angle neutron scattering: further evidence for a 30 nm diameter super coil in dilute solutions.

S Bram, P Baudy, J Lepault, D Hermann.   

Abstract

Intact chromatin, chromatin minus histone H1, and nuclease digestion fragments have been studied by very small angle neutron scattering. The results are not consistent with a straight chain of nucleosomes and require the presence of a higher order coiling in monovalent salt solutions. The data are interpretable by a structure having a cross section radius of gryration of 8.5 +/- 1 nm, which suggests an outer diameter for a coil of nucleosomes of 27 +/- 3 nm.
