Specificity & Comments

It recognizes a protein of 15kDa, identified as Gross cystic disease fluid protein 15 (GCDFP-15). It is a major protein component of benign breast gross cysts. It is a known marker of breast cancer, as it is found in approximately 50% of all breast cancer specimens. GCDFP-15, also known as PIP, for prolactin inducible protein, is a prolactin and androgen controlled protein. This antibody is useful in the identification of metastatic breast carcinoma, or fluid analysis.

Known Applications & Suggested Dilutions

Flow Cytometry (0.5-1ug/million cells)
Immunofluorescence (0.5-1ug/ml)
Western Blotting (0.5-1ug/ml)
Immunohistology (Formalin-fixed) (0.5-1ug/ml for 30 minutes at RT)
(Staining of formalin-fixed tissues is enhanced by boiling tissue sections in 10mM Tris buffer with1mM EDTA, pH 9.0, for 10-20 min followed by cooling at RT for 20 minutes)
Optimal dilution for a specific application should be determined.

Positive Control

HepG2 Cells. Breast or Pancreas.
