重组Anti-Vinculin抗体[EPR8185] (ab129002)

Western blot: Anti-VCL antibody [EPR8185] (ab129002) staining at 1/10000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab129002 was shown to bind specifically to VCL. A band was observed at 124 kDa in wild-type A431 cell lysates with no signal observed at this size in VCL knockout cell line. To generate this image, wild-type and VCL knockout A431 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween^® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Flow cytometry overlay histogram showing wild-type A-431 (green line) and VCL knockout A-431 stained with ab129002 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilised with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS containing 10% normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab129002) (1x 10⁶ in 100μl at 0.00032 μg/ml (1/6249999)) for 30min at 22°C.

The secondary antibody Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed was incubated at 1/4000 for 30min at 22°C

Isotype control antibody Recombinant Rabbit IgG, monoclonal [EPR25A] - Isotype Control was used at the same concentration and conditions as the primary antibody (wild-type A-431 - black line, VCL knockout A-431 - grey line). Unlabelled sample was also used as a control (this line is not shown for the purpose of simplicity).

Acquisition of >5000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter.

Immunofluorescent staining of HEK293 cells (fixed in 4% PFA, permeabilized with 0.1% Triton X 100) using purified ab129002 at a dilution of 1/50. An Alexa Fluor^® 488 goat anti-rabbit antibody (ab150077) was used as the secondary at a dilution of 1/1000 and the cells were counter stained with DAPI. The negative controls are shown in the bottom middle and right hand panels. For negative control 1, the primary was used and then goat anti-mouse IgG was used at a dilution of 1/500. For negative control 2, a mouse primary antibody (ab7291) and anti-rabbit secondary antibody (ab150077) were used.

Intracellular Flow Cytometry analysis of 293 (human embryonic kidney epithelial) cells labeling Vinculin (red) with ab129002 at a 1/200 dilution. Cells were fixed with 4% paraformaldehyde and permeabilized with 90% methanol. A goat anti-rabbit IgG (Alexa Fluorr^® 488) (ab150077) was used as the secondary antibody at a 1/2000 dilution. Black - Rabbit monoclonal IgG (ab172730). Blue (unlabeled control) - Cells without incubation with the primary and secondary antibodies. 

ab129002 (purified) at 1/20 immunoprecipitating vinculin in HeLa cells. Lane 1: HeLa whole cell lysate (10 µg). Lane 2: HeLa whole cell lysate (10 µg). Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab129002 in HeLa whole cell lysate. For western blotting, a HRP-conjugated goat anti-rabbit antibody was used as the secondary antibody (1/1000).
