A modified fractionation procedure for avian erythrocyte histones

The fractionation method of Vidali and Neelin for avian erythrocyte histones was modified to reduce the time required to obtain clean fractions of serine-rich and arginine-rich histones. Histones were extracted from washed nuclei in one step with 0.20 M HCI. The lysine-rich and the moderately lysine-rich histones were fractionated by cation-exchange chromatography but the serine-rich and arginine-rich histones were eluted together. These histones were separated by subsequent exclusion chromatography.Peer reviewed: YesNRC publication: Ye
