| 摘要 |
The present invention provides improved methods for assessing the level of MGMT activity in a variety of biological preparations. MGMT, a DNA repair enzyme, can reduce the chemotherapeutic efficacy of alkylating agents by repairing the damage that alkylating agents do to tumor cell DNA. The methods of the present invention can be used, inter alia, to measure MGMT levels and to thereby predict the clinical response to alkylating agents. The present invention includes three preferred assays for assessment of MGMT activity: (1) the immunoassay technique, (2) the labeled O<SUP>6</SUP>-BG technique, and (3) the fluorescence polarization technique. Kits useful for the performance of such assays are also provided.
