WA-1 reacts with human and other mammalian p21, a tumor suppressor protein, belonging to the CDI family. The intracellular protein p21 is a 21 kDa protein, also known as wild-type p53-activated fragment 1 (WAF1). It is an inhibitor of cyclin-dependent kinases (Cdks) and of proliferating-cell nuclear antigen (PCNA). It is induced by wild type p53, but not by mutated p53, by mezerein (anti-leukemic compound) and by interferon-ß. 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 and thyroid carcinoma).

Positive control: MCF7 cells, UV treated fibroblasts, HeLa cells, skin, colon, or breast carcinoma.
