Anti-GALNT5 antibody produced in rabbit，100UL，HPA008963-100UL，Sigma

General description

GALNT5 (N-acetylgalactosaminyltransferase 5) is a highly tissue specific protein. It predominantly localizes to the cytoplasm of gastric epithelial and gastric cancer cells. This gene localizes to human chromosome 2q24.

Immunogen

polypeptide N-acetylgalactosaminyltransferase 5

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

GALNT5 (N-acetylgalactosaminyltransferase 5) glycosylates restricted types of substrates. It is capable of interacting with Golgi proteins, by projecting its catalytic domain in the lumen of the Golgi complex. It might play a role in maintaining the structure of gastric mucosa, and less differentiated gastric tumor tissues show low expression of this protein. Its low expression is linked with TNM classification, and functions as an independent prognostic marker for poor outcome in gastric cancer patients. In breast cancer, missense mutation in this gene results in the loss of enzymatic function of this GALNT5 protein. This gene is also up-regulated in hepatoblastomas when compared to the expression in differentiated livers.

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
