GCDFP-15 Antibody (Immunohistochemistry)

The GCDFP-15 (Gross Cystic Disease Fluid Protein-15) Antibody is a highly specific
immunohistochemical marker used to identify apocrine-differentiated breast carcinomas.
GCDFP-15 is a 15 kDa glycoprotein found in apocrine epithelial cells of the breast ducts, as well as in
the axillary, salivary, vulvar, and eyelid glands.

In pathology, GCDFP-15 shows strong cytoplasmic staining in breast adenocarcinomas.
Meanwhile, it is usually negative in lung, colorectal, and mesothelial tumors.
As a result, GCDFP-15 is extremely valuable for distinguishing metastatic breast carcinoma
from other adenocarcinomas of unknown origin.
