Application Abreviews Notes
ICC 1/250 - 1/500.
WB 1/1000 - 1/10000. Predicted molecular weight: 15 kDa.
IHC-P 1/250 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target


    • Predicted band size : 15 kDa
      Observed band size : 55 kDa (why is the actual band size different from the predicted?)

      Lane 1: Wild type HAP1 whole cell lysate (20 µg)
      Lane 2: Apg12 knockout HAP1 whole cell lysate (20 µg)
      Lane 3: HeLa whole cell lysate (20 µg)
      Lane 4: HCT116 whole cell lysate (20 µg)

      Lanes 1 - 4: Merged signal (red and green). Green - ab109491 observed at 55 kDa. Observed band shows Apg12-ATG5 conjugation. Red - loading control, ab8245, observed at 37 kDa.

      Ab109491 was shown to specifically react with Apg12 in wild-type cells along with additional cross-reactive bands. The band was not seen in Apg12 knockout HAP1 cells. Wild-type and Apg12 knockout samples were subjected to SDS-PAGE.  Ab109491 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10000 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 1/10000 dilution for 1 hour at room temperature before imaging.
