To facilitate studies on the functional significance of histone...

BACKGROUND Excessive proliferation is one of the first steps in oncogenic activation and one of the most important biological features defining the aggressiveness of tumors. Quantifying the proportion of tumor cells in S-phase by means of flow cytometry has shown, in the past, to be useful for defining high-risk subgroups in breast cancer. Several antigens closely associated with proliferation ...
