Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 23 kDa (predicted molecular weight: 22 kDa).
IHC-P 1/800.

Antigen retrieval is recommended. See IHC antigen retrieval protocols.

For unpurified use at 1/250- 1/500.

  • 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.

      Belongs to the MGMT family.

    • Anti-MGMT antibody [EPR4397] (ab108630) at 1/5000 dilution (Purified) + MCF7 (Human breast adenocarcinoma epithelial cell) whole cell lysates at 15 µg

      Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/20000 dilution

      Predicted band size: 22 kDa
      Observed 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 - unpurified 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.

    • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human lung cancer tissue sections labeling MGMT with purified ab108630 at 1:800 dilution (0.94 µg/ml). Heat mediated antigen retrieval was performed Perform heat mediated antigen retrieval using Citrate buffer, pH 6.0. ImmunoHistoProbe one step HRP Polymer (ready to use) was used as the secondary antibody. Negative control: PBS instead of the primary antibody. Hematoxylin was used as a counterstain.

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