Anti-B4GALT3 antibody produced in rabbit

B4GALT3 (UDP-Gal:βGlcNAc β 1,4- galactosyltransferase, polypeptide 3) belongs to a family of seven members, called β-1,4-galactosyltransferase (β-1,4-GalT). It is expressed in a wide range of human tissues. Its expression in fetal brain is much higher than that in adult brain. This gene is located on human chromosome 1q23. The coding region of this gene consists of one initiation codon, preceding a sequence coding for a putative hydrophobic transmembrane region. The predicted encoded protein is a type II transmembrane protein, containing a cytoplasmic N-terminal of four residues. It has a stem region, an eighteen residue transmembrane region, and a catalytic domain made of 371 amino acids, containing four potential N-linked glycosylation sites.

Anti-B4GALT3 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

B4GALT3 (UDP-Gal:βGlcNAc β 1,4- galactosyltransferase, polypeptide 3) enzyme catalyzes the synthesis of poly-N-acetyllactosamine. However, its extension capacity of poly-N-acetyllactosamine is poor, and it adds the first galactose residue to poly-N-acetyllactosamine chain. It enhances metastasis and invasiveness of neuroblastoma cells, via the modulation of signaling and glycosylation of β1-integrin. It is overexpressed in neuroblastoma cells, and predicts poor prognosis for the same. B4GALT3 expression is also negatively correlated with metastasis in 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.
