Applications

Our Abpromise guarantee covers the use of ab108989 in the following tested applications.

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).
IP 1/10 - 1/100.
  • Application notes
    Is unsuitable for ICC/IF or IHC-P.

    • 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.
    • Cellular localization
      Nucleus.

        ab108989 was shown to specifically react with MGMT when MGMT knockout samples were used. Wild-type and MGMT knockout samples were subjected to SDS-PAGE. ab108989 and ab8245 (loading control to MGMT) 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.

      Many thanks for your reply. The answer was perfect.
      I was also wondering whether you have any information regarding the concentration of the particular Lot that I have?

      Thank you for your reply.

      ab108989 is atissue culture supernatant, not a purified antibody.
      Unpurified antibodies, such as those sold as whole antiserum, ascites or tissue culture supernatant will not have a concentration stated on the dat...
