Gene Information

human ... PRG2(5553)

General description

PRG2 (proteoglycan 2, pro eosinophil major basic protein)/ major basic protein (MBP) is a cationic protein of human eosinophil specific granules, that is present in crystalloid cores of these granules. MBP is a helminthotoxin. PRG2 is mapped to human chromosome 11q12.

Immunogen

proteoglycan 2, bone marrow (natural killer cell activator, eosinophil granule major basic protein) 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.
Anti-PRG2 antibody produced in rabbit has been used in immunohistochemistry.

Biochem/physiol Actions

Eosinophils are white blood cells, which play a major role in innate immunity and in the pathogenesis of several inflammatory and neoplastic disorders. Accumulation of PRG2 (proteoglycan 2, pro eosinophil major basic protein)/ major basic protein (MBP) impairs epithelial cells in vitro, in vivo and ex vivo. It plays an important role in mediating cytotoxicity and allergic disorders like asthma. PRG2 helps to enhance smooth muscle reactivity by affecting vagal muscarinic M2 receptor, that helps in the progression of airway hyperreactivity.

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.
