Anti-TPBG antibody produced in rabbit

TPBG (trophoblast glycoprotein) is an oncofetal glycoprotein with a molecular weight of 72kDa. It is rarely expressed in normal adult tissues, but it is seen to be expressed in multiple cancerous tissues. It is also expressed by trophoblast cells and placenta. It is a cell surface protein. Its extracellular domain is highly glycosylated and contains eight leucine-rich repeats (LRRs). This protein is composed of 420 amino acids and contains a single transmembrane domain.

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.

TPBG (trophoblast glycoprotein) interacts with human trophoblast. This protein is highly expressed in pancreatic ductal adenocarcinoma (PDAC), which is linked with tumor-node-metastasis (TNM) stage of the tumor. It is also involved in metastasis in PDAC. This protein promotes EMT (epithelial-mesenchymal transition) and CXCL12/CXCR4 (C-X-C motif chemokine ligand/CXC receptor) chemotaxis, and inhibits canonical Wnt/β-catenin. It is overexpressed in malignant pleural mesothelioma (MPM), and has potential as an immunotherapy target in the same.

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.
