- Аннотация: The experiments undertaken in order to verify the trioxsalen-crosslinking method suggested by Russev and Vassilev for isolation of eukaryotic replication origins are described. It was found that the preparation of viral DNA isolated by the above mentioned method from CV-1 cells lytically infected with SV40 was not enriched in sequences including SV40 replication origin. The hybridization pattern of DNA preparation isolated by the trioxsalen-crosslinking procedure from chicken erythroblastosis cells with the cloned fragments of globin gene domain was found to be identical to those of the total DNA probe. The DNA fraction enriched in replication origins was isolated from the same cells with the aid of nascent DNA strand extrusion method by Zannis-Hadjopoulos et al. The hybridization pattern of this DNA fraction with the cloned fragments of chicken alpha-globin gene domain was different from those of total DNA. Taking together, the results of our experiments demonstrate that trioxsalen-crosslinking procedure does not lead to the isolation of replication origins from the objects studied in the present investigation.
