    • Predicted band size : 123 kDa

      Lane 1: Wild-type HAP1 cell lysate (40 µg)
      Lane 2: PI3 Kinase p110 beta knockout HAP1 cell lysate (40 µg)
      Lane 3: Jurkat cell lysate (40 µg)
      Lane 4: K562 cell lysate (40 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab32569 observed at 125 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab32569 was shown to recognize PI3 Kinase p110 beta when PI3 Kinase p110 beta knockout samples were used, along with additional cross-reactive bands. Wild-type and PI3 Kinase p110 beta knockout samples were subjected to SDS-PAGE. Ab32569 and ab8245 (loading control to GAPDH) were diluted at 1/500 and 1:10,000 dilution respectively and incubated overnight at 4C. Blots were developed with IRDye® 800CW Goat anti-Rabbit IgG (H + L) and IRDye® 680 Goat anti-Mouse IgG (H + L) secondary antibodies at 1:10,000 dilution for 1 hour at room temperature before imaging.
