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

BAG (BCL2 associated athanogene) family molecular chaperone regulator-3 (BAG3) protein has been described as an anti-apoptotic and pro-autophagic factor. Presence of HIV (Human immunodeficiency virus)-1 TAT protein up-regulates BAG3 levels, stimulating autophagy in human glial cells. BAG3 bind to major vault protein (MVP) and contribute to apoptosis resistance through activation of extracellular signal-regulated kinase1/2 (ERK1/2). This mechanism is responsible for chemotherapy resistance in breast cancer. BAG3 is overexpressed in lung carcinomas and exerts an anti-apoptotic effect in resistance to chemotherapy. Mutation in BAG3 causes myofibrillar myopathy, characterized by the formation of protein aggregates and myofibrillar disintegration.

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.
