Application CommentsAlthough the amino acid sequence of MDM2 predicts a protein with a molecular mass of approximately 54 kDa, MDM2 protein migrates on SDS/PAGE with an apparent mobility of 90 kDa.

Immunoblotting Protocol
MDM2 (Ab-1) can be used to detect MDM2 by Western blot of proteins previously separated by SDS/PAGE and electrophoretically transferred onto nitrocellulose membranes. The proteins are reacted with the monoclonal antibody and visualized using an HRP conjugated goat anti-mouse antibody with chemiluminescent detection.

• 3% Non-fat Dry Milk in PBST

Procedure
1. Lyse cells in ELB Buffer. (Alternatively, cells can be lysed in RIPA Buffer or directly into 1x Laemmli Sample Buffer).
2. Electrophorese 50-100 µg lysate using a 7% acrylamide gel.
3. Transfer the protein samples from the polyacrylamide gel onto a nitrocellulose membrane using an electroblotting apparatus.
4. Block the membrane for 1 h in PBST containing 3% non-fat dry milk at room temperature with rocking. Use about 1 ml per cm2 of membrane.
5. Incubate the membrane with 1 µg/ml Anti-MDM2 (Ab-1) Mouse mAb (IF2) in 3% non-fat dry milk/ PBST for 1 h at room temperature with rocking.
6. Wash the membrane 3 times, 15 min each, in PBST at room temperature with rocking.
7. Incubate the membrane with HRP conjugated goat anti-mouse IgG heavy and light chain antibody, diluted according to the supplier’s instructions, in 3% non-fat dry milk/ PBST at room temperature for 1 h.
8. Wash the membrane 4 times, 15 min each, in PBST at room temperature with rocking.
9. Develop the membrane using chemiluminescent detection reagents according to manufacturer instructions.
10. Expose the membrane to film for ten minutes. Adjust subsequent exposure times as needed.

    DescriptionPurified mouse monoclonal antibody (see application references). Recognizes the ~90 kDa (apparent MW) MDM2 protein. Also recognizes isoforms at ~57 and ~74/76 kDa.
    BackgroundIncreased expression of proto-oncogenes due to gene amplification can lead to cellular transformation in the absence of other mutagenic events. Recently, a novel gene termed MDM2, first identified in mouse as a small acentromeric extrachromosomal element, was shown to become oncogenic upon amplification and tumorigenic when overexpressed in NIH3T3 and Rat2 cells. The human homolog of MDM2 gene has been isolated and mapped to chromosome 12q13-q14, a region that is found to be amplified in human sarcomas. Sequence analysis of the murine, rat, and human MDM2 genes suggests that MDM2 may be involved in transcriptional regulation. MDM2 contains two putative metal-binding motifs, one of which shares similarity to known zinc finger transcriptional activators. MDM2 also contains a putative nuclear localization signal and an acidic domain of the type found in transcriptional activators. A functional role for MDM2 has recently been identified on the basis of experiments which demonstrate that MDM2 forms a stable complex with p53 in vivo. Furthermore, over-expression of MDM2 inhibits the ability of wild type p53 to stimulate expression of target genes, and this inhibition appears to result from MDM2 binding to the acidic activation domain of p53, thereby preventing p53 from directly contacting the transcriptional machinery. Interestingly, wild type p53 appears to positively regulate expression of the MDM2 gene. MDM2 amplification has been observed in sarcomas, and direct analysis of the MDM2 and p53 genes in sarcomas indicates that one or the other but not both of these genes is mutated in 70% of the tumors. Thus, it appears that genetic alterations in either p53 or MDM2 represent alternative mechanisms for inactivating the same growth suppressive pathway. Regulation of MDM2 expression by p53 also represents a potential feed back control of p53 function.
