Anti-PPA1 antibody produced in rabbit，100UL，HPA019878-100UL，Sigma

General description

PPA1 (Inorganic pyrophosphatase 1) is a 32kDa protein consisting of an aspartate-rich region. It is expressed in all the tissues and mapped on chromosome 10.

Immunogen

Inorganic pyrophosphatase recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

Biochem/physiol Actions

PPA1 (pyrophosphatase 1) facilitates hydrolytic conversion of pyrophosphate to orthophosphate. Study shows its tumor-specific protein expression in gastric cancer cells, thus, it has been suggested that PPA1 can be a potential tumor-specific marker in gastric cancers. PPA1 is also involved in the regulation of pancreatic ductal HCO₃^- secretion. In addition, it also controls anion exchange (AE) activity by activating CFTR (cystic fibrosis transmembrane conductance regulator)/pendrin at the apical membrane and inhibiting the basolateral AE by cAMP agonists.

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
