A method of screening a cell for the onset of senescence or a senescent state therein comprises detecting a p21-E2F complex in the cell, an elevation in the complex as compared to a normal cell indicating the onset of senescence or a senescent state in the cell. Isolated complexes comprised of p21 and E2F are also disclosed. The complexes stably bind to DNA and are useful, among other things, for binding DNA. |
