    • Lane 1: Wild type HAP1 whole cell lysate (40 µg)
      Lane 2: PIK3CD knockout HAP1 whole cell lysate (40 µg)
      Lane 3: Jurkat whole cell lysate (40 µg)
      Lane 4: K562 whole cell lysate (40 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab109006 observed at 120 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab109006 was shown to specifically react with PIK3CD in wild-type HAP1 cells. No band was observed when PIK3CD knockout samples were used. Wild-type and PIK3CD knockout samples were subjected to SDS-PAGE. Ab109006 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/1000 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 1/10,000 dilution for 1hr at room temperature before imaging.
