Changes in chromatin chain flexibility during condensation induced by sodium chloride, as evidenced by electric dichroism.

Abstract

The electric linear dichroism of chicken erythrocyte chromatin has been measured as a function of NaCl concentration in the 1-28 mM ionic strength range, using a specially designed Kerr cell with reduced pathlength, and thus, smaller electrode surface. This allowed the determination of the dichroism of compact chromatin in conditions where artifacts due to… (More)
