p53 is a 53 kDa nuclear phosphoprotein that acts as a tumor suppressor protein, and is involved in inhibiting cell proliferation when DNA damage occurs. The gene for p53 is the most commonly mutated gene yet identified in human cancers. Missense mutations occur in tumors of the colon, lung, breast, ovary, bladder and several other organs. The mutant p53 is overexpressed in a variety of transformed cells and wild-type p53 forms specific complexes with several viral oncogenes including SV40 large T, E1B from adenovirus, and E6 from human papilloma virus. Wild type p53 plays a role as a checkpoint protein for DNA damage during the G1/S-phase of the cell cycle. However, it is still unclear, whether point mutated forms of p53 are simple null mutants and/or dominant negatively acting proteins.

Clone DO-7 recognizes human wildtype and mutant p53. It cross-reacts with bovine p53 but does not cross-react with mouse or rat p53. Clone DO-7 recognizes an epitope between amino acids 1-45 of all known forms of human p53. Human recombinant p53 protein was used as immunogen. Wildtype 53 proteins have a very short half-life and are usually not detectable with monoclonal antibodies in normal tissues. Clone DO-7 was initially characterized by immunoprecipitation, western blot analysis, immunohistochemistry of frozen and formalin-fixed paraffin-embedded tissue sections, and flow cytometric analysis.

Clone 27-35 is an isotype control monoclonal antibody specific for hapten dansyl (5-[dimethylamino] naphthalene-1-sulfonyl). This hapten is not expressed on human cells or human cell lines.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

Recommended Assay Procedures

Positive control cell lines include SK-BR-3 human breast carcinoma cells (ATCC HTB-30), HT-29 human colon adenocarcinoma (ATCC HTB-38) and A431 human vulval carcinoma cells (ATCC CRL-1555). MCF-7 human breast carcinoma cells (ATCC HTB-22) are suggested as a negative control.

Product Notices

  1. This antibody has been optimized and preassayed with its matched isotype control to be used at the recommended volume of 20 ul/test. Titration of the reagents or substituting with other (non-matched) isotype control is NOT recommended.
  2. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  4. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.
  5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at
  6. Please refer to for technical protocols.
