[Histones of Salmonidae fishes. Comparative study of histones from different species and intraspecies variability of Oncorhynchus nerka H1].

The comparative electrophoretic properties of erythrocyte histones from 7 Salmonidae species were investigated. Using Na-SDS gel electrophoresis, it was shown that all the species studied possess the erythrocyte-specific fraction of histone H5. High resolution gel electrophoresis in acetic acid--urea gels demonstrated differences in the subfractional composition of histone H1 from erythrocytes and liver of O. nerka. The analysis of the sample of 40 individuals from the same population revealed the existence of intraspecies polymorphism in histone H1 subfractional composition.
