Background information

MDM2 is over-expressed in many tumors. Its principal function is the ubiquitination and degradation of p53 tumor suppressor protein. This monoclonal antibody also recognizes a peptide epitope around Thr-216 of murine MDM2 when Thr-216 is unphosphorylated. SMP14 also cross reacts with some cytokeratins (6, 14 & 16). This is only a problem when working with certain epithelial cells and not fibroblasts.

Physical form

Purified mouse monoclonal IgGκ in buffer containing 0.1 M Tris-Glycine (pH 7.4, 150 mM NaCl) with 0.05% sodium azide.


Immunoprecipitation Analysis: A representative lot was used by an independent laboratory for this application. (Changgong, L., et al. (2002). Molecular and Cellular Biology. 22(21):7562-7571.)


This antibody recognizes MDM2.


His-tagged recombinant protein corresponding to human MDM2.

Species Reactivity Notes

Demonstrated to react with human. Predicted to react with mouse based on 100% sequence homology.

Quality Assurance

Evaluated by Western Blot in MCF-7 cell lysate.

Western Blot Analysis: 0.5 µg/ml of this antibody detected MDM2 on 10 µg of MCF-7 cell lysate.
