Detection of p53 in inflammatory tissue and lymphocytes using immunohistology and flow cytometry: a critical comment.

Abstract

Demonstration of p53 by western blot is more sensitive and reliable than immunohistology and flow cytometry. Western blot is the gold standard for the demonstration of p53 expression and should be used, whenever possible, to confirm p53 expression in normal tissue shown by immunohistology or flow cytometry. All other reports on p53 expression, especially those obtained using antibodies with an unusual staining pattern must be interpreted with caution.
