Anti-PIP antibody produced in rabbit，100UL，HPA009177-100UL，Sigma

General description

PIP (prolactin-induced protein) is a secretd glycoprotein, which exists as a monomer. This protein is found in exocrine glands, gross cystic disease and breast cancers showing apocrine features. The corresponding gene is localized to human chromosome 7q34-q35. This protein is localized to cytoplasm and plasma membrane. PIP has a molecular weight of 14kDa and is a component of various body fluids including human tear fluid.

Immunogen

Prolactin-inducible protein precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-PIP antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

PIP (prolactin-induced protein) gene is activated transcriptionally by androgen and by prolactin in a post-transcriptional manner. It is also regulated by lactogenic hormones produced by pituitary gland and other steroids. This protein is expressed in breast cancers and is linked with ER⁺ (estrogen receptor), PgR⁺ (progesterone receptor), low tumor grade and relapse-free survival. It is inactivated in advanced stages of tumor. The expression of this protein is up-regulated in keratoconus (KC), which is a bilateral degenerative disease of the cornea and is characterized by scarring, bulging of the cornea and thinning of stroma. PIP, therefore, might function as a biomarker for KC disease.

Features and Benefits

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
