  ab81208 Anti-Cortactin antibody [EP1922Y] was shown to specifically react with Cortactin in wild-type HEK-293T cells. Loss of signal was observed when knockout cell line Human CTTN (Cortactin) knockout HEK-293T cell line ab266819 (knockout cell lysate Human CTTN (Cortactin) knockout HEK-293T cell lysate ab257147) was used. Wild-type and Cortactin knockout samples were subjected to SDS-PAGE. ab81208 and Anti-GAPDH antibody [6C5] - Loading Control (Anti-GAPDH antibody [6C5] - Loading Control ab8245) were incubated overnight at 4°C at 1 in 50000 Dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

  ab81208 staining Cortactin in wild-type HAP1 cells (top panel) and Cortactin knockout HAP1 cells (bottom panel). The cells were fixed with 4% formaldehyde (10min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab81208 at 1/1000 dilution and Alexa Fluor® 594 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker ab195889 at 1/250 dilution (shown in pseudo colour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed ab150081) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

  Western blot - Anti-Cortactin antibody [EP1922Y] (ab81208)

  Lanes 1 - 4: Merged signal (red and green). Green - ab81208 observed at 62 kDa. Red - loading control, Anti-GAPDH antibody [6C5] - Loading Control ab8245, observed at 37 kDa.
  

  ab81208 was shown to specifically react with Cortactin in wild-type HAP1 cells along with additional cross reactive bands. No band was observed when Cortactin knockout samples were examined. Wild-type and Cortactin knockout samples were subjected to SDS-PAGE. ab81208 and Anti-GAPDH antibody [6C5] - Loading Control ab8245 (loading control to GAPDH) were both diluted 1/2000 and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.

  Overlay histogram showing HeLa cells stained with ab81208 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab81208, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (Goat Anti-Rabbit IgG H&L (DyLight® 488) preadsorbed ab96899) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1μg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed.
