    R&D Systems mouse anti fvii antibody
    Analysis of the association between TF, <t>fVII</t> and PAR2 on the surface of cells: MDA-MB-231 cells (10 3 ) were seeded out into 35 mm-glass based μ-dishes and incubated overnight. Cells were then fixed with 4% ( v / v ) paraformaldehyde for 15 min, washed three times with PBS for 5 min and blocked with Duolink blocking buffer for 1 h. The cells were then incubated overnight at 4 °C with combinations of antibodies as follows: the cells were probed with a mouse anti-fVII <t>antibody</t> <t>(321621;</t> 10 µg/mL) together with a rabbit anti-TF antibody (FL295; 5 µg/mL) to examine the interaction between fVII and TF. Another set of cells were probed with a rabbit anti-TF antibody (FL295; 5 µg/mL) and a mouse anti-PAR2 antibody (SAM11; 20 μg/mL) to examine the association of TF and PAR2 proteins. Finally, to test the proximity between fVII and PAR2, the cells were probed with a polyclonal rabbit anti-fVII antibody (10 µg/mL) together with mouse anti-PAR2 antibody (SAM11). ( A ) The dishes were washed three times with PBS and PLA performed according to the manufacturer’s instructions. The cells were stained with DAPI (2 μg/mL) and Phalloidin-FITC (2 µg/mL). Images were acquired using a Zeiss Axio Vert.A1 inverted fluorescence microscope with a ×40 magnification. A different representative of the control samples in which one primary antibody was substituted with a isotype control is presented in each of the figures. ( B ) The number of red fluorescent events and nuclei were determined as incidence/cell in 10 fields of view from each assay using the ImageJ program. ( n = 4; * = p < 0.05 vs. the control).

    Analysis of the association of TF and PAR2 in the presence and absence of fVIIa: Sets of MDA-MB-231 cells (10 5 ) cells were transfected with a set of Silencer Select Pre-designed siRNA specific for the coagulation factor VII or a control siRNA (200 nM) using Trans IT-2020 transfection reagent and incubated for 48 h at 37 °C. ( A ) The knock-down was optimised beforehand by Western blot using a rabbit polyclonal anti-fVII antibody 1:2000 ( v / v ) and developed with a goat anti-rabbit antibody 1:4000 ( v / v ) (also see ). The membranes were analysed by the ImageJ program to determine the level of expression of fVII as well as the active subunits of fVIIa protein. ( n = 3; * = p < 0.05 vs. Non-transfected sample). ( B ) MDA-MB-231 cells (10 3 ) were seeded out into 35 mm-glass based μ-dishes overnight. Sets of cells were transfected and incubated as above. Some transfected cells were supplemented with purified fVIIa (10 nM) and other untransfected sets of cells were treated with apixaban (1 µg/mL). All cells were then fixed with 4% ( v / v ) paraformaldehyde for 15 min, washed three times with PBS for 5 min and blocked with Duolink blocking buffer for 1 h. The cells were then incubated overnight at 4 °C with a rabbit anti-TF antibody (FL295; 5 µg/mL) and a mouse anti-PAR2 antibody (SAM11; 20 μg/mL).

Images were acquired using a Zeiss Axio Vert.A1 inverted fluorescence microscope with a ×40 magnification. A different representative of the control samples in which one primary antibody was substituted with a isotype control is presented in each of the figures. ( B ) The number of red fluorescent events and nuclei were determined as incidence/cell in 10 fields of view from each assay using the ImageJ program. ( n = 4; * = p < 0.05 vs. the control).

    Analysis of the association between TF, fVII and PAR2 on the surface of cells: MDA-MB-231 cells (10 3 ) were seeded out into 35 mm-glass based μ-dishes and incubated overnight. Cells were then fixed with 4% ( v / v ) paraformaldehyde for 15 min, washed three times with PBS for 5 min and blocked with Duolink blocking buffer for 1 h. The cells were then incubated overnight at 4 °C with combinations of antibodies as follows: the cells were probed with a mouse anti-fVII antibody (321621; 10 µg/mL) together with a rabbit anti-TF antibody (FL295; 5 µg/mL) to examine the interaction between fVII and TF. Another set of cells were probed with a rabbit anti-TF antibody (FL295; 5 µg/mL) and a mouse anti-PAR2 antibody (SAM11; 20 μg/mL) to examine the association of TF and PAR2 proteins.

    Analysis of the association of TF and PAR2 in the presence and absence of fVIIa: Sets of MDA-MB-231 cells (10 5 ) cells were transfected with a set of Silencer Select Pre-designed siRNA specific for the coagulation factor VII or a control siRNA (200 nM) using Trans IT-2020 transfection reagent and incubated for 48 h at 37 °C. ( A ) The knock-down was optimised beforehand by Western blot using a rabbit polyclonal anti-fVII antibody 1:2000 ( v / v ) and developed with a goat anti-rabbit antibody 1:4000 ( v / v ) (also see ). The membranes were analysed by the ImageJ program to determine the level of expression of fVII as well as the active subunits of fVIIa protein. ( n = 3; * = p < 0.05 vs. Non-transfected sample). ( B ) MDA-MB-231 cells (10 3 ) were seeded out into 35 mm-glass based μ-dishes overnight. Sets of cells were transfected and incubated as above. Some transfected cells were supplemented with purified fVIIa (10 nM) and other untransfected sets of cells were treated with apixaban (1 µg/mL). All cells were then fixed with 4% ( v / v ) paraformaldehyde for 15 min, washed three times with PBS for 5 min and blocked with Duolink blocking buffer for 1 h. The cells were then incubated overnight at 4 °C with a rabbit anti-TF antibody (FL295; 5 µg/mL) and a mouse anti-PAR2 antibody (SAM11; 20 μg/mL).
