Histones F2al extracted from normal and neoplastic cells possess similar amino acid compositions. Tryptic and chymotryptic peptides of the F2al histones have identical chromato-electrophoretic R(F) values. It is concluded that histones F2al from various sources have similar overall structures. The observed differences in the ratios of in-N-monomethyl- and(More)
OBJECTIVES Cryopreserved valve allografts used in congenital cardiac surgery are associated with a significant cellular and humoral immune response. This might be reduced by removal of antigenic cellular elements (decellularization). The aim of this study was to determine the immunologic effect of decellularization in a rat allograft valve model. METHODS(More)
OBJECTIVE Cryopreserved allograft cardiovascular tissue elicits a strong cellular and humoral response in recipients; this may accelerate the deterioration of the allograft and complicate future heart transplantation. Juvenile sheep are the standard model for in vivo valve research and have been used to investigate the allogeneic immune response to cardiac(More)
Purified chromatin isolated from lymphocytic cells derived from patients with acute leukemia, or other lymphoproliferative disorders has been compared with chromatin isolated from normal human lymphocytic cells by gel electrophoresis and differential gradient ultracentrifugation. Thermal denaturation studies showed higher Tm values for chromatin from(More)
