Description
This antibody recognizes a 21kDa protein, identified as the p21 or p21WAF1 tumor suppressor protein. This antibody is highly specific and shows no cross-reaction with other closely related mitotic inhibitors. p21 is a specific inhibitor of cdk's and a tumor suppressor involved in the pathogenesis of a variety of malignancies. The expression of this gene acts as an inhibitor of the cell cycle during G1 phase and is tightly controlled by the tumor suppressor protein p53. p21 expression is induced by the wild type, but not mutant, p53. Normal cells generally display a rather intense nuclear expression. Loss of p21 expression has been reported in many carcinomas (gastric carcinoma, non-small cell lung carcinoma, thyroid carcinoma) .
