The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 23 kDa (predicted molecular weight: 22 kDa).
IHC-P 1/250 - 1/500. Antigen retrieval is recommended.
  • Application notes
    Is unsuitable for Flow Cyt,ICC or IP.
  • Target

    • Function
      Involved in the cellular defense against the biological effects of O6-methylguanine (O6-MeG) in DNA. Repairs alkylated guanine in DNA by stoichiometrically transferring the alkyl group at the O-6 position to a cysteine residue in the enzyme. This is a suicide reaction: the enzyme is irreversibly inactivated.
    • Sequence similarities
      Belongs to the MGMT family.

    • Predicted band size: 22 kDa

      Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: MGMT knockout HAP1 cell lysate (20 µg)
      Lane 3: MCF7 cell lysate (20 µg)
      Lane 4: Jurkat cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab108630 observed at 22 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab108630 was shown to specifically react with MGMT when MGMT knockout samples were used. Wild-type and MGMT knockout samples were subjected to SDS-PAGE. ab108630 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/2000 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.

    Leider ist es so, wie ich gestern schon vermutete: Wir haben die Antikörper- Konzentration in dem Zellkultur- Überstand leider nicht bestimmt.
