General description

Wild-type p53 is present in the nucleus of all normal mammalian cells where it appears to be involved in the regulation of cell proliferation. The normal protein has a very short half-life and is present in only minute amounts in normal tissues and cells. In contrast, mutant p53 protein produced by malignant cells is usually a product of a point mutation in the p53 gene leading to substitution of a single amino acid that significantly prolongs the half-life of the protein. The accumulation of high levels of p53 is a potential novel marker for malignancy.

Immunohistochemistry Analysis: A 1:50 dilution of this antibody detected p53 in normal human brain tissue.

Immunoprecipitation Analysis: A representative lot from an independent laboratory detected p53 in IP (Lu, X., et al. (1992). Cell. 70(1):153-161.).

Immunohistochemistry Analysis: A representative lot from an independent laboratory detected p53 in dorsal skin samples from animal trunks (Kramata, P., et al. (2005). Cancer Res. 65(9):3577-3585.) and in certain human cancer tissues (Cordon-Cardo, C., et al, (1991). 51(23 Pt 1):6372-6380.).
