Description

Images of negatively stained chromatin fibers prepared from tandem arrays of a nucleosome positioning sequence reconstituted with purified histones. These samples contained 61 repeats of a 197 bp DNA sequence reconstituted with core histones alone (leftmost image) plus different amounts of linker histone H5 (33%, 67%, and 100% respectively). See: Fig 3A in Routh et al. (2008) Nucleosome repeat length and linker histonen stoichiometry determine chromatin fiber structure. Proc Natl Acad Sci USA 105:8872-8877.

Technical Details

Reconstituted chromatin was fixed with 0.1% glutaraldehyde for 30 min, deposited on glow discharged carbon films, negatively stained with aqueous uranyl acetate, and examined with a Philips 2085 TEM operated at 80 KV.
