Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Tissue Factor antibody [EPR22548-232] (AB228968)

Immunohistochemical analysis of paraffin-embedded human kidney tissue labeling Tissue Factor with ab228968 at 1/500 dilution, followed by ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Positive staining in human renal glomerulus (PMID : 7684196). The section was incubated with ab228968 for 30 mins at RT. The immunostaining was performed on a Leica Biosystems BOND^® RX instrument. Counterstained with hematoxylin.

Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101).

Perform heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20mins.

Flow Cytometry - Anti-Tissue Factor antibody [EPR22548-232] (AB228968)

Flow cytometric analysis of MCF7 (human breast adenocarcinoma epithelial cell, Left) / A431 (human epidermoid carcinoma epithelial cell, Right) labeling Tissue Factor with ab228968 at 1/500 (red) compared with a Rabbit monoclonal IgG (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat anti rabbit IgG (Alexa Fluor^® 488, ab150077), at 1/2000 dilution was used as the secondary antibody.

Low expression : MCF7 (PMID : 24137414, PMID : 28938620).

Gated on viable cells.

Immunoprecipitation - Anti-Tissue Factor antibody [EPR22548-232] (AB228968)

Tissue Factor was immunoprecipitated from 0.35 mg A431 (human epidermoid carcinoma epithelial cell) whole cell lysate with ab228968 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab228968 at 1/1000 dilution. VeriBlot for IP for detection (HRP) (ab131366), was used Detection Reagent at 1/5000 dilution.

Lane 1 : A431 whole cell lysate 10 μg (Input).
Lane 2 : ab228968 IP in A431 whole cell lysate.
Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab228968 in A431 whole cell lysate.

Blocking/Dilution buffer : 5% NFDM/TBST.
Exposure time : 30 seconds.

Western blot - Anti-Tissue Factor antibody [EPR22548-232] (AB228968)

ab228968 was shown to specifically react with Tissue Factor in wild-type HAP1 cells as signal was lost in Tissue Factor knockout cells. Wild-type and Tissue Factor knockout samples were subjected to SDS-PAGE. ab228968 and ab181602 (Rabbit anti-GAPDH loading control) were incubated 1 hour at room temperature at 1/1000 dilution and 1/200,000 dilution respectively. Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/100,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD^® ChemiDoc™ MP instrument using the ECL technique.

The molecular weight observed is consistent with what has been described in the literature (PMID : 28938620).

Low expression : MCF-7 (PMID : 24137414, 28938620).

Exposure times : Lanes 1-2 : 70 secs; Lanes 3-6 : 3.25 secs.
