  Immunocytochemistry/ Immunofluorescence - Anti-Cytokeratin 14 antibody [EP1612Y] - BSA and Azide free (ab243907)

  This data was developed using the same antibody clone in a different buffer formulation (Anti-Cytokeratin 14 antibody [EP1612Y] ab51054). Anti-Cytokeratin 14 antibody [EP1612Y] ab51054 staining KRT14 in wild-type A431 cells (top panel) and KRT14 knockout A431 cells (bottom panel). The cells were fixed with 100% methanol (5 min) then 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 Anti-Cytokeratin 14 antibody [EP1612Y] ab51054 at 1/100 dilution and Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291 (Mouse monoclonal to alpha Tubulin) at 1/1000 dilution 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) and a goat secondary antibody to mouse IgG (Alexa Fluor^® 594) (Goat Anti-Mouse IgG H&L (Alexa Fluor® 594) preadsorbed ab150120) at 2 μg/ml (shown in red). Nuclear DNA was labelled in blue with DAPI.

  Western blot - Anti-Cytokeratin 14 antibody [EP1612Y] - BSA and Azide free (ab243907)

  This data was developed using the same antibody clone in a different buffer formulation (Anti-Cytokeratin 14 antibody [EP1612Y] ab51054).
  

  Lanes 1 - 4: Merged signal (red and green). Green - Anti-Cytokeratin 14 antibody [EP1612Y] ab51054 observed at 49 kDa. Red - loading control, Anti-GAPDH antibody [6C5] - Loading Control ab8245 (Mouse anti-GAPDH antibody [6C5]) observed at 37kDa.

  Anti-Cytokeratin 14 antibody [EP1612Y] ab51054 was shown to react with Cytokeratin 14 in wild-type A431 cells in Western blot. Loss of signal was observed when KRT14 knockout sample was used. Wild-type A431 and KRT14 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3% milk in TBS-T (0.1% Tween^®) before incubation with Anti-Cytokeratin 14 antibody [EP1612Y] ab51054 and Anti-GAPDH antibody [6C5] - Loading Control ab8245 (Mouse anti-GAPDH antibody [6C5]) overnight at 4°C at a 1 in 10000 dilution and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (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.

  ICC/IF image of ab51504 stained A431 (Human epidermoid carcinoma cell line) cells.
  

  The cells were fixed in 100% methanol (5 min) and then incubated in 1% BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilize the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab51504, 1/100 dilution) overnight at +4°C. The secondary antibody (green) was Goat Anti-Rabbit IgG H&L (DyLight® 488) preadsorbed ab96899, DyLight^® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor^® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43 μM.

  This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (Anti-Cytokeratin 14 antibody [EP1612Y] ab51054)

  The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Triton 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 (Anti-Cytokeratin 14 antibody [EP1612Y] ab51054, 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 was rabbit IgG (monoclonal) (1μg/1x10⁶cells) used under the same conditions. Acquisition of >5,000 events was performed.

  This antibody gave a positive signal in A431 cells fixed with 4% paraformaldehyde/permeabilized in 0.1% PBS-Triton used under the same conditions.
