Product Overview
This rabbit polyclonal antibody recognizes alpha-2-HS-glycoprotein (gene AHSG) in human and rat samples and is validated for ELISA, flow cytometry, IHC, ICC/IF and Western blot. The predicted molecular weight is 39.3 kDa, and the supplier reports an observed band at about 55–60 kDa.
Fetuin-A (AHSG, alpha-2-HS-glycoprotein) is an abundant plasma protein made mainly by the liver. It binds calcium phosphate and helps prevent unwanted mineral deposition, and it is studied in bone mineralization, vascular calcification, insulin resistance and inflammation.

Samples with a confirmed band (WB): human placenta tissue, human hcct tissue, human hccp tissue, rat plasma.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human liver cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in citrate buffer (pH 6).
Samples with a confirmed signal (flow cytometry): HepG2 cells.
Immunogen
Synthetic peptide from the N-terminal region of human fetuin A. It differs from the mouse and rat sequences at thirteen residues.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt describes alpha-2-HS-glycoprotein as a secreted protein. Tissue expression noted by UniProt (human): Synthesized in liver and selectively concentrated in bone matrix. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
