Product Overview
This rabbit polyclonal antibody targets tissue factor (gene F3) in human samples and is validated for ELISA, flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 33.1 kDa, and the supplier reports an observed band at about 50 kDa.
Tissue factor (F3, CD142) is a transmembrane glycoprotein that starts the extrinsic pathway of blood coagulation. When exposed to blood it binds factor VII/VIIa, and the complex activates factors IX and X. Tissue factor is expressed by cells outside the vessel wall and can be induced on monocytes and tumor cells, linking coagulation with inflammation and cancer.

Samples with a confirmed band (WB): human A431 cells, human Hacat 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, 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 placenta 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).
Samples with confirmed staining (ICC/IF): Figure 3 IF analysis of tissue.
Samples with a confirmed signal (flow cytometry): A431 cells.
Immunogen
Recombinant human Tissue Factor fragment (Ser33–Ser295), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 57.6% and 57.2%, respectively.
Reactivity Notes
The supplier lists reactivity with human. Tissue expression noted by UniProt (human): Lung, placenta and pancreas. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
