Wilms' tumor 1 (WT1) protein
This mouse monoclonal antibody reacts on WT1 protein, which has been identified in proliferative mesothelial cells, malignant mesothelioma, ovarian cystadeno-carcinoma, gonadoblastoma, nephroblastoma and desmoplastic small round cell tumor. The WT1 gene is normally expressed in fetal kidney and mesothelium, and its expression has been suggested as a marker for Wilm's tumor and mesothelioma. Lung adenocarcinoma is rarely positive with this antibody.
