Monoclonal Anti-MGMT (O6-Methylguanine-DNA Methyltransferase) (mouse IgG1 isotype) is derived from the MGMT-214 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice. O6-Methylguanine-DNA Methyltransferase (MGMT) is a DNA repair protein. MGMT gene is mapped to human chromosome 10q26.3. It comprises a C-terminal helix-turn-helix motif and arginine “finger,” flip in its active site. MGMT is expressed ubiquitously.
Specificity
Monoclonal Anti-MGMT (O6-Methylguanine-DNA Methyltransferase) recognizes human MGMT(approx. 25 kDa).
Immunogen
recombinant human MGMT.
Application
Monoclonal Anti-MGMT antibody produced in mouse may be used in enzyme-linked immunosorbent assay (ELISA) and immunoblotting.
Biochem/physiol Actions
O6-Methylguanine-DNA Methyltransferase (MGMT) removes O6-alkyl-guanine, primarily O6-methylguanine lesions from damaged DNA. It is a major contributor to cellular protection from the mutagenic, carcinogenic, and cytotoxic effects of DNA alkylation. The mechanism of MGMT action is based on the transfer of the alkyl group from the DNA to a unique acceptor cysteine residue in the protein. MGMT is frequently classified as a suicide protein. Because the reaction irreversibly inactivates the enzyme, the repair capacity for O6-methylguanine is dependent on the number of MGMT molecules in the cell. There is a correlation between the occurrence of cancer in various tissues and the lack of the MGMT enzyme. High levels of MGMT result in reduced tumor events and resistance of tumors to alkylating agents.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
Storage and Stability
For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. Storage in frost-free freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

Chemoresistance has been a significant problem affecting the efficacy of drugs targeting tumors for decades. MGMT, known as O6-methylguanine-DNA methyltransferase, is a DNA repair enzyme that plays an important role in chemoresistance to alkylating agents. Hence, MGMT is considered a
Mitochondrial DNA is constantly exposed to oxidative injury. Due to its location close to the main site of reactive oxygen species, the inner mitochondrial membrane, mtDNA is more susceptible than nuclear DNA to oxidative damage. The accumulation of DNA damage
Alkylating agents constitute a major class of frontline chemotherapeutic drugs that inflict cytotoxic DNA damage as their main mode of action, in addition to collateral mutagenic damage. Numerous cellular pathways, including direct DNA damage reversal, base excision repair (BER) and

O(6)-methylguanine (O(6)mG) is a potent mutagenic and procarcinogenic DNA lesion. Organisms have evolved with a DNA repair mechanism that largely ameliorates the deleterious effects of O(6)mG through a direct reversal mechanism by a protein termed O(6)-methylguanine-DNA methyltransferase (MGMT). However, the
