Immunohistochemistry of paraffin-embedded human liver cancer using FNab10100(MGMT antibody) at dilution of 1:200
Background
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.
