![Analysis of Mass Spec data (dashed-line) of fractions stained with p21WAF1 MS-QAVA™ monoclonal antibody [Clone: HJ21] (solid-line), reveals that less than 11.3% of signal is attributable to non-specific binding of anti-p21WAF1 [Clone HJ21] to targets other than CDKN1A protein. Even frequently cited antibodies have much greater non-specific interactions, averaging over 30%.

| General Description of p21WAF1. | |
| This MAb recognizes a 21kDa protein, identified as the p21WAF1 tumor suppressor protein. It is highly specific to p21, shows no cross-reaction with other closely related mitotic inhibitors. p21WAF1 is a specific inhibitor of cdk s, 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, is tightly controlled by the tumor suppressor protein p53. Its expression is induced by the wild type, but not mutant, p53 suppressor protein. Normal cells generally display a rather intense nuclear p21 expression. Loss of p21 expression has been reported in many carcinomas (gastric carcinoma, non-small cell lung carcinoma, thyroid carcinoma). | |
