Description_x000D_ General description_x000D_ SVEP1 (Sushi, von Willebrand factor type A, EGF and pentraxin domain-containing protein 1) also called as polydom or SEL-OB (selectin-like osteoblast-derived protein) is expressed primarily in osteogenic cells. The gene coding for protein is localized to human chromosome 9q32._x000D_ SVEP1 protein consists of multiple domains such as vWA (von Willebrand factor type A), EGF (epidermal growth factor), PTX (pentraxin), and HYR (hyalin repeat) domains, and complement control protein (CCP) modules which are also called sushi domains._x000D_ Immunogen_x000D_ Sushi, von Willebrand factor type A, EGF and pentraxin domain-containing protein 1 Precursor recombinant protein epitope signature tag (PrEST)_x000D_ Application_x000D_ All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry._x000D_ 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.

LLC_x000D_ Biochem/physiol Actions_x000D_ SVEP1 (Sushi, von Willebrand factor type A, EGF and pentraxin domain-containing protein 1) plays a vital role in cell adhesion process and immune response mediated by complement system. This secretory protein serves as a marker for pre-fated satellite cells of skeletal mucle. SVEP1 protein acts as a ligand for integrin α9β1 receptor._x000D_ Features and Benefits_x000D_ 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._x000D_ Every Prestige Antibody is tested in the following ways:_x000D_ • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues._x000D_ • Protein array of 364 human recombinant protein fragments._x000D_ • Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)_x000D_ Linkage_x000D_ Corresponding Antigen APREST75350.
