Product Overview
This rabbit polyclonal antibody recognizes tissue factor pathway inhibitor (gene TFPI) in human samples and is validated for Western blot. The predicted molecular weight is 35.0 kDa, and the supplier reports an observed band at about 45 kDa.
Tissue factor pathway inhibitor (TFPI) is a Kunitz-type protease inhibitor that controls the start of blood coagulation. It first binds and inhibits factor Xa and then blocks the tissue factor–factor VIIa complex, and it is studied in hemostasis, thrombosis and hemophilia research.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human) |
|---|
Samples with a confirmed band (WB): HeLa cells, MCF-7 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.
Immunogen
Recombinant human TFPI fragment (Asn253–Met304), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 51.1% and 53.2%, respectively.
Reactivity Notes
The supplier lists reactivity with human. Tissue expression noted by UniProt (human): Mostly in endothelial cells. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
