Anti-Hepatocyte Specific Antigen (OCH1E5) Primary Antibody is a mouse monoclonal antibody that recognizes both benign and malignant liver including such tumors as hepatoblastoma, hepatocellular carcinoma, and hepatic adenoma. It recognizes both normal adult and fetal liver tissue. The typical pattern is a granular cytoplasmic staining. This antibody is useful in differentiating hepatocellular carcinomas with adenoid features from adenocarcinomas, either primary in the liver or metastatic lesions to the liver. In recognizing hepatoblastoma, it is useful in differentiating this entity from other small round cell tumors.
