Chicken erythrocyte chromatin and nuclear envelope antigens.
Chromatin and inner layer nuclear envelope were isolated from chicken erythrocyte nuclei. Two antisera against dehistonized chromatin and nuclear envelope of chicken erythrocytes were obtained. Using the antiserum against dehistonized chromatin of erythrocytes we found: the presence of the antigens at approximate mol. wts of 56,000 and 77,000 tightly bound with DNA and characteristic of only erythrocyte chromatin; localized antigens at approximate mol. wts of 63,000, 68,000 and 92,000 tightly bound with DNA and common only for chromatin and nuclear envelope of chicken erythrocytes; heterogeneity of the antigens tightly bound with DNA. Using the antiserum against inner layer nuclear envelope we did not find antigens specific only for nuclear envelope and absent in erythrocyte chromatin. Some of the antigens were present in the control preparations of chicken liver chromatin and may be regarded as being species specific.
