  • Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
    Lane 2: TK1 knockout HAP1 whole cell lysate (20 µg)
    Lane 3: Jurkat whole cell lysate (20 µg)
    Lane 4: MOLT4 whole cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab76495 observed at 25 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab76495 was shown to specifically react with TK1 in wildtype HAP1 cells. No band was observed when TK1 knockout samples were examined. Wild-type and TK1 knockout samples were subjected to SDS-PAGE.  Ab76495 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/5000 dilution and 1/10,000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20,000 dilution for 1 hour at room temperature before imaging.

  • Immunohistochemical analysis of paraffin-embedded human tonsils using 1/100 ab76495
  • Overlay histogram showing HeLa cells stained with ab76495 (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 (ab76495, 1/50 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

Thank you for contacting Abcam.

The main difference between ab76495 and ab91651 is that they will have different epitope recognition sites.

Also for ab76495, we guarantee it to react with mouse and human tissue in the following appl...
