    • Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: QPRT knockout HAP1 cell lysate (20 µg)
      Lane 3: HepG2 cell lysate (20 µg)
      Lane 4: Human fetal brain cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab171944 observed at 35 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab171944 was shown to specifically react with QPRT when QPRT knockout samples were used. Wild-type and QPRT knockout samples were subjected to SDS-PAGE. ab171944 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/10 000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776 secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.
