RDI Divison of researchd Industries Intl offers a wide line of antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

Positive Control: CCRF-CEM,1 Molt-4,1 Raji,1 HeLa CCL2,1 Rh18, 1 or HT-29 2 cells. Liver tissue expresses high levels while brain and bone marrow have low levels of MGMT protein.
Cellular Localization: Nuclear and cytoplasmic
Background: It recognizes a protein of 25kDa, identified as MGMT (O 6 -methylguanine-DNA methyltransferase). Cancer chemotherapeutic alkylating agents (e.g. BCNU, CCNU, DTIC, procarbazine, temozolomide), act by inducing formation of lethal cross-links at the O 6 - alkylguanine position in DNA. MGMT transfers alkyl adducts from the O 6 -position of guanine in DNA (prior to cross-link formation) to a cysteine residue in its own sequence, thereby restoring DNA to its intact state. This transfer inactivates the MGMT enzyme and is irreversible; hence the level of MGMT in a cell is directly proportional to the level of DNA- damage it can tolerate. Because MGMT repairs the potentially cytotoxic, antitumor lesions induced in DNA by alkylating agents, tumors with low or no levels of MGMT will predictably be responsive to such drug therapy. Conversely, tumors with high levels of MGMT will likely be drug resistant. In normal tissues, MGMT acts as a suppressor of mutation and carcinogenesis. Abnormally low levels of MGMT in normal individuals/tissues may be an early marker of susceptibility to cancer.
