Verification Images

Western blot analysis was performed on protein extracts (25 μg) from HepG2 (lane 2) using Factor VIII antibody. Proteins were transferred onto a 0.22 μm PVDF membrane using the Trans-Blot® Turbo™ system for 13 min. The membrane was then blocked with 5% nonfat milk in TBST (HY-K1025) for 1 h at room temperature. The primary antibody (1:1000) and loading control antibody β-actin Antibody (HRP) (HY-P80993) (1:10000) were diluted in 5% nonfat milk in TBST and incubated with the membrane overnight at 4°C. After washing, the membrane of primary antibody was incubated with HRP-conjugated goat anti-rabbit/mouse IgG secondary antibody (HY-P8001/HY-P8004) (1:5000) diluted in 5% nonfat milk in TBST for 1 h at room temperature. Protein bands were visualized using an Ultra High Sensitivity ECL detection kit (HY-K1005). -
Immunohistochemical analysis of paraffin-embedded human colon cancer using Factor VIII antibody. The section was pre-treated using heat mediated antigen retrieval with EDTA (pH 9.0) for 14 minutes. The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with TBST, and then probed with the primary antibody (HY-P85156, 1/200) for 1 hour at room temperature. The detection was performed using Polymer HRP-conjugated Goat Anti-Mouse/Rabbit lgG(H&L) secondary antibody (HY-P83652). DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX. -

Background
-
Function
Factor VIII (FVIII) is an essential blood coagulation protein, is a key component of the fluid phase blood coagulation system. Factor VIII is also a large procoagulant glycoprotein and a metal ion-dependent heterodimer that circulates in plasma in a noncovalent complex with von Willebrand factor. Factor VIII absence causes a severe bleeding disorder.
