Renal Cell Carcinoma
Full Description
Identifies renal cell carcinoma (RCC) antigen. In normal kidney, staining is localized along the brush border of proximal tubules. RCC antigen is also seen on the luminal surfaces of breast ducts and lobules, epididymal epithelium, within parathyroid cytoplasm, and focally in thyroid colloid. Most primary and metastatic renal cell carcinomas express this marker, while other normal tissues do not show cross-reactivity.
