Product Overview
Clone ABAO-1 is a rabbit monoclonal antibody that recognizes alpha-2-macroglobulin (gene A2M) in human samples and is validated for Western blot and IHC. The predicted molecular weight is 163.3 kDa, and the supplier reports an observed band at about 163 kDa.
Alpha-2-macroglobulin (A2M) is a large plasma protein that inhibits proteases from all major catalytic classes. When a protease cuts its bait region, A2M changes shape and traps the enzyme, and the complex is then cleared from the circulation, so A2M is studied in inflammation, coagulation and protease regulation.

Validated Applications
| Western blot | 1:500–1:2000 |
|---|---|
| Immunohistochemistry | 1:50–1:200 |
Samples with a confirmed band (WB): human HepG2 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 8% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human liver cancer tissue, human liver 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 EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide based on the sequence of human A2M.
Reactivity Notes
The supplier lists reactivity with human. UniProt describes alpha-2-macroglobulin as a secreted protein. Tissue expression noted by UniProt (human): Secreted in plasma. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
