Glycoproteins present in the fraction of chromatin proteins loosely bound to DNA from hamster, chicken and frog liver cells

There are numerous glycoproteins recognized by Concanavalin A (ConA) and Galanthus nivalis agglutinin (GNA) in 0.35 mol/l NaCl soluble fraction of chromatin proteins loosely bound to DNA from hamster, chicken and frog liver cells. Results of our detailed comparative analysis show a marked similarity between liver chromatin glycoproteins from the examined animals. The presence of similar chromatin glycoproteins in different animal species may indicate that they play an important universal role in the liver cells.
