Anti-Mouse MDM2 Phospho-Ser185 Antibody

Cat. Num. AAA4156720

• Gene Names: MDM2; HDMX; hdm2; ACTFS
• Reactivity: Mouse
• Applications: Western Blot, Immunohistochemistry, ELISA
• Purity: Affinity Purified
• Synonyms: MDM2; Polyclonal Antibody; Anti-Mouse MDM2 Phospho-Ser185 Antibody; Mouse MDM2 pS185; anti-MDM2 antibody

• Host: Rabbit
• Reactivity: Mouse
• Clonality: Polyclonal
• Isotype: IgG
• Specificity: This affinity-purified antibody is directed against the phosphorylated form of mouse MDM2 protein at the pS185 residue. The product was affinity purified from monospecific antiserum by immunoaffinity purification. Antiserum was first purified against the phosphorylated form of the immunizing peptide. The resultant affinity purified antibody was then cross-adsorbed against the non-phosphorylated form of the immunizing peptide. Reactivity occurs against Mouse MDM2 pS185 protein and the antibody is specific for the phosphorylated form of the protein. Reactivity with non-phosphorylated mouse MDM2 is minimal by ELISA and western blot. A BLAST analysis was used to suggest minimal cross reactivity with MDM2 homologues from other sources.
• Purity/Purification: Affinity Purified
• Form/Format: Liquid; PBS, pH 7.4 with 0.05% sodium azide.
• Concentration: 1ug/ul (varies by lot)
• Sequence Length: 257

• Applicable Applications for anti-MDM2 antibody: Western Blot (WB), Immunohistochemistry (IHC), ELISA (EIA)
• Application Notes: This affinity purified antibody has been tested for use in ELISA and by western blot. Specific conditions for reactivity should be optimized by the end user. Expect bands approximately 102 kDa in size corresponding to phosphorylated MDM2 protein by western blotting in the appropriate cell lysate or extract.
• Immunogen: This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to aa 177-198 of mouse MDM2.
• Preparation and Storage: This product is stable for several weeks at 4 degree C as an undiluted liquid. Dilute only prior to immediate use.; For extended storage, aliquot contents and freeze at-20 degree C or below. Avoid cycles of freezing and thawing. Expiration date is one (1) year from date of receipt.

Related Product Information for anti-MDM2 antibody

MDM2 is a nuclear phosphoprotein with an apparent molecular mass of 90 kD that forms a complex with the p53 tumor suppressor protein. Human MDM2 was identified as a homologous product of the 'murine double minute 2' gene (mdm2). The MDM2 gene enhances the tumorigenic potential of cells when it is overexpressed and encodes a putative transcription factor. Forming a tight complex with the p53 gene, the MDM2 oncogene can inhibit p53-mediated transactivation. MDM2 binds to p53 and amplification of MDM2 in sarcomas leads to escape from p53-regulated growth control. This mechanism of tumorigenesis parallels that for virus-induced tumors in which viral oncogene products_recover bind to and functionally inactivate p53. Overexpression of the MDM2 oncogene was found in leukemias. Inactivation of tumor suppressor genes leads to deregulated cell proliferation and is a key factor in human tumorigenesis. MDM2 interacts physically and functionally with the retinoblastoma (RB) protein and can inhibit its growth regulatory capacity. Both RB and p53 can be subjected to negative regulation by the product of a single cellular protooncogene. The interference of binding to p53 prevents the interaction of MDM2 and its regulation of the transcriptional activity of p53 in vivo. Direct association of p53 with the cellular protein MDM2 results in ubiquitination and subsequent degradation of p53. MDM2-p53 complexes were preferentially found in S/G2M phases of the cell cycle. The MDM2 gene is alternatively spliced, producing 5 additional splice variant transcripts from the full length MDM2 gene. Four out of five of these alternatively spliced forms (MDM2a-MDMd) are missing substantial portions of the p53 binding domain and retain the acidic domain and the zinc-finger domains. The fifth and smallest transcript (MDM2e) retains the largest spliced region encoding the p53 binding domain; however, it lacks the nuclear localization signal, the acidic domain and zinc-finger domains. The alternatively spliced transcripts tend to be expressed in tumorigenic tissue, whereas the full-length MDM2 transcript is expressed in normal tissue.

NCBI Description

This gene encodes a nuclear-localized E3 ubiquitin ligase. The encoded protein can promote tumor formation by targeting tumor suppressor proteins, such as p53, for proteasomal degradation. This gene is itself transcriptionally-regulated by p53. Overexpression or amplification of this locus is detected in a variety of different cancers. There is a pseudogene for this gene on chromosome 2. Alternative splicing results in a multitude of transcript variants, many of which may be expressed only in tumor cells.
