Anti-PIP Antibody

Supplied as a 100 µl vial at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, this unconjugated rabbit polyclonal antibody from Antibodies.com detects human prolactin-inducible protein (PIP) in western blot, immunohistochemistry, and immunofluorescence workflows. PIP is a small secreted glycoprotein expressed in apocrine glands and used as a marker for apocrine differentiation in breast cancer research, Paget disease, and salivary, lacrimal, or sweat gland biology studies. The polyclonal format presents multiple epitopes on the target, supporting reliable visualization in fixed tissue sections and confirmation of expression in cultured human cell lines. The glycerol-containing buffer allows storage at standard freezer conditions and retains activity through repeated freeze-thaw cycles, making the reagent convenient for labs running both routine western blot screens and tissue-based immunohistochemistry.
