Immunogen This purified antibody was prepared from Rabbit serum after repeated immunizations with a recombinant Human Fetuin (Alpha-2-HS glycoprotein) processed to remove a 40 amino acid residue bridging peptide resulting in the mature form of the protein.
Specificity This product is an IgG fraction antibody purified from monospecific antiserum by a multistep process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above. Assay by Immunoelectrophoresis resulted in a single precipitin arc against anti-Goat Serum.
Purification Multistep process.
Alternative Name Alpha-2-HS-glycoprotein
Background Human Fetuin (2-Heremans-Schmid-glycoprotein or alpha2-HS-glycoprotein) is a major plasma glycoprotein predominantly synthesized in the liver. Human fetuin is named after its bovine homolog. Fetuins are found in most mammals. Human fetuin is a negative acute-phase protein, normal circulating levels in adults (300-600 µg/ml) fall significantly (30-50%) during injury and infection. The biological role of fetuin is unknown, although it has been implicated as an immunomodulator that can participate in stimulation of bacterial phagocytosis by neutrophils and promotion of endocytosis by mouse macrophages. Hepatocytes are the principal cell source of circulating fetuin, but it also is expressed by monocyte/macrophages. Fetuins occur in large amounts in blood and cerebrospinal fluid and accumulate to high concentrations in calcified bone. The fetuin promoter region has several potential interleukin 6-responsive elements, and its synthesis is down-regulated during injury and inflammation. Fetuin is an acidic glycoprotein with three Nlinked and three O-linked oligosaccharide chains, whose terminal sugar residues are rich in sialic acid (Nacetylneuraminic acid), contributing to its net negative charge. A role for fetuin as a carrier of bioactive molecules has been proposed based on observations that it binds and carries Ca2+ ion. Fetuin is implicated in bone remodeling, immune function and may play a role in tumor progression of certain cell types. Fetuin plays a role as an anti-inflammatory agent by suppressing the release of TNF from stimulated macrophages. Fetuin also interacts with members of the matrix metalloprotease family of zinc dependent secreted transmembrane proteins that degrade basement membranes and extracellular matrix components. The biological activity of fetuin is mediated through its direct interaction with other proteins. Fetuin down-regulates a number of receptor tyrosine kinase family members. A motif within fetuin has homology to the TGF-beta receptor type II. Circulating human plasma fetuin is partly phosphorylated which implies that phosphorylated fetuin may have a physiological function in vivo. Human fetuin isolated from plasma is a two- chain molecule consisting of a A-chain of 322 amino acid residues (53 kDa) and a B-chain of 27 residues (5 kDa). The carboxy terminal 40 amino acids of the A chain constitute a bridging peptide that may be removed proteolytically in vivo. A single mRNA encodes both the A and B chains. The apparent molecular weight of intact human fetuin is 58 kDa.

Application Notes This purified polyclonal antibody reacts with human fetuin by ELISA (1/40,000-1/200,000)and Western blot (1/10,000-1/20,000). Although not tested, this antibody is likelyfunctional in Immunohistochemistry and Immunoprecipitation. A doublet band or slightlylower molecular weight band (see Figure 1, lane 1) may be visible by western blot due toproteolytic processing, variable glycosylation and/or phosphorylation. Proteolytic processing may include the removal of a 40 amino acid residue bridgingpeptide from the A and B chains of fetuin in vivo. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

anti-alpha-2-HS-Glycoprotein (AHSG) antibody Immunoblot of Fetuin..,.Anti-Human Fetuin antibody, generated by immunization with mature protein, was tested by immunoblot against fetuin in purified preparations and in human plasma..,.Lane 1 contains 250 ng of purified human fetuin. Lane 2 contains 5 ul of a 1:50 dilution of human serum. Dilution of Anti-Human Fetuin antibody between 1:10,000 and 1:20,000 showed strong reactivity by.,.immunoblot. In this blot the antibody was used at a 1:10,000 dilution incubated 1 h at room temperature in 1% BSA in TTBS. Detection occurred using a 1:5,000 dilution of IRDye™800 conjugated Donkey anti-Goat IgG for 45 min at room temperature. LICOR's Odyssey® Infrared Imaging System was used to scan and process the image. Other detection systems will yield similarresults.
