Detection of Human Fetuin A/AHSG antibody by Western Blot.

Detection of Human Fetuin A/AHSG by Western Blot.

Western blot shows human plasma. PVDF membrane was probed with 0.1 µg/mL of Goat Anti-Human Fetuin A/AHSG Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1184) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Fetuin A/AHSG at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Fetuin A/AHSG antibody in Human Liver by Immunohistochemistry (IHC-P).

Fetuin A/AHSG in Human Liver.

Fetuin A/AHSG was detected in immersion fixed paraffin-embedded sections of human liver array using Goat Anti-Human Fetuin A/AHSG Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1184) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

Detection of Human Fetuin A/AHSG by Simple WesternTM.

Simple Western lane view shows lysates of HepG2 human hepatocellular carcinoma cell line, Human Liver, loaded at 0.2 mg/mL. A specific band was detected for Fetuin A/AHSG at approximately 63 kDa (as indicated) using 2.5 µg/mL of Goat Anti-Human Fetuin A/AHSG Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1184). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Fetuin A/AHSG

Human Fetuin A, also known as alpha 2-Heremans-Schmid glycoprotein, is encoded by the AHSG gene. It is a major plasma protein and a member of the cystatin superfamily of protease inhibitors (1, 2). It is expressed by hepatocytes, the principal cell source, and by monocyte/macrophages (3). The major form of plasma Fetuin A corresponds to a disulfide bond-linked two chains derived from the single chain (4). Human Fetuin A has a number of functions. It is a negative acute-phase protein with normal circulating levels in adults (300-600 μg/mL), which fall significantly (30-50%) during injury and infection (5). It enhances entry of cationic inhibitors into macrophages (6). It inhibits both insulin receptor autophosphorylation and undesirable calcification (6, 7). The purified rhFetuin A corresponds to the single chain, which can be converted to the two-chain form by rhFurin (R&D Systems, Catalog # 1503-SE) in vitro. However, the conversion does not enhance its inhibitory activity against rhCathpesin V, a cysteine protease.
