Description
RCC antibody is a 200 kDa glycoprotein (gp200) expressed in renal epithelial cells, stains the brush border of proximal renal tubules in human kidneys. Renal cell carcinoma antibody reactivity has been described in up to 93% of primary human renal cell carcinomas and 84% of renal cell carcinoma metastases. The clone 66.4.C2 antibody has also been used to help make a diagnosis of renal cell carcinoma in a horse with a mass of unknown origin. Gp200 is also expressed in breast tubules and ducts, the surface of epididymal tubular epithelia, and the colloid of thyroid follicles
