Abstract:
The polyacrylamide gel electrophoresis of total histone extracted from young (3 months) and old (26-27 months) rat tissues does not show age-related differences in the pattern of the main five histones. However, when the lysine-rich F1 histone was extracted from chromatin separately by perchloric acid and purified by Biogel P-60 column chromatography from chromatin of rat liver and spleen, the polyacrylamide gel electrophoresis did show obvious age changes in the distribution of F1, F1o, and F1(00) subfractions. In liver chromatin the increase of rat-specific methionine-containing subfraction (F1met.) was also found.
