Table 1 Expression of the apoptosis-related cell surface antigen Annexin V in mock-transfected and wild-type p53-expressing K562 cells

K562 cells were incubated at an initial concentration of 200,000 cells/ml in culture medium at the permissive temperature. After 2 days, cells were subjected to analysis of Annexin V by flow cytometry. Values shown are percentage of cells expressing Annexin V.
