Product Overview
Clone 6D12 is a mouse monoclonal antibody that recognizes fibrinogen beta chain (gene FGB) in human samples and is validated for Western blot and IHC. The predicted molecular weight is 55.9 kDa, and the supplier reports an observed band at about 56 kDa.
Fibrinogen beta chain (FGB) is one of the three chains of fibrinogen, the liver-derived plasma protein that is converted by thrombin into fibrin. Fibrin polymers form the structural scaffold of blood clots and support early wound repair. FGB is studied in coagulation, thrombosis and inflammation.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
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): 5–20% gradient SDS-PAGE under reducing conditions, 50 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 1:10000, 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 EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide from the middle region of human FGB. It differs from the mouse sequence at three residues and from the rat sequence at five residues.
Reactivity Notes
The supplier lists reactivity with human. UniProt describes fibrinogen beta chain as a secreted protein. Tissue expression noted by UniProt (human): Detected in blood plasma (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
