Anti-B4GALT1 antibody produced in rabbit

B4GALT1 (UDP-Gal:βGlcNAc β 1,4- galactosyltransferase, polypeptide 1) belongs to a family of type II transmembrane proteins called glycosyltransferases, which resides in Golgi apparatus. This family consists of seven members, from GALT1 to GALT7. B4GALT1 has two isoforms, having different cellular locations, because of differences in their cytoplasmic domains. The long isoform is localized to the cell surface, whereas the short isoform is found in the Golgi apparatus. This gene is located on human chromosome 9p13, and codes for a protein containing 398 amino acids. It is expressed in most tissues, excluding adult brain and fetal heart and brain.

β-1,4-Galactosyltransferase 1 recombinant protein epitope signature tag (PrEST)

Anti-B4GALT1 antibody produced in rabbit has been used in immunofluorescence microscopyand immunoblotting.

B4GALT1 (UDP-Gal:βGlcNAc β 1,4- galactosyltransferase, polypeptide 1) is responsible for the synthesis of galactose β-1,4-N-acetylglucosamine (Galβ1-4GlcNAc) groups on glycoproteins, on their N-linked sugar chains. This is performed by the short isoform of B4GALT1, which resides in Golgi bodies. The long isoform, localized to the cell surface, helps in cell adhesion, by interacting with N-acetylglucosamine containing oligosaccharides, which are found in the extracellular matrix. In patients with rheumatoid arthritis, it is involved in the inflammatory response in the synovial tissue. B4GALT1 plays an important role in the proliferation of MCF-7 breast cancer cells by interacting with estrogen receptor. It is methylated and down-regulated in colorectal cancer patients, and hence, can act as a marker of invasive phenotype of colorectal cancer.

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.
