TP53 Antibody validated by WB using human DU145 cells at 1:2,000.

• 

  DU145 cells were lysed in IP lysis buffer: 20 mM HEPES, 1% Triton X-100, 150 mM NaCl, 1 mM EDTA, 1 mM EGTA, 100 mM NaF, 10 mM Na4P2O7, 1 mM Na3VO4, 0.2 mM PMSFAmount of Protein per well: 30 ugPrimary antibody conditions: 1:2000 in 5% milk/TBST buffer, overnight at 4æCSecondary antibody conditions: 1 to 5000 in 5% milk/TBST buffer, 1 hour at room temperatureTP53 is strongly supported by BioGPS gene expression data to be expressed in Human DU145 cells

  Figure 1. Binding of p53-specific antibodies to the p21 promoter. U20S (p53+) cells were treated with 0.5 uM Doxorubicin for 14 hrs to induce DNA damage and hence activate p53. In parallel, PLKO cells (U2OS cells with stable shRNA-mediated knockdown of p53) were treated similarly and were used as negative control. Thedata for p21 promoter were normalised to actin (control for non-specific binding of DNA to the antibodies).

• Background: Tumor protein p53 responds to diverse cellular stresses to regulate target genes that induce cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. p53 protein is expressed at low level in normal cells and at a high level in a variety of transformed cell lines, where it's believed to contribute to transformation and malignancy. p53 is a DNA-binding protein containing transcription activation, DNA-binding, and oligomerization domains. It is postulated to bind to a p53-binding site and activate expression of downstream genes that inhibit growth and/or invasion, and thus function as a tumor suppressor. Mutants of p53 that frequently occur in a number of different human cancers fail to bind the consensus DNA binding site, and hence cause the loss of tumor suppressor activity. Alterations of this gene occur not only as somatic mutations in human malignancies, but also as germline mutations in some cancer-prone families with Li-Fraumeni syndrome
