p53 Antibody (PAb 240) Summary

Gel-purified p53-beta-galactosidase fusion protein containing murine p53 from aa 14-389 (derived from pSV53C cDNA clone).
The epitope has been mapped between amino acids 213 and 217 on human p53. The epitiope may be conformational as it reacts with mutant p53 in nondenatured form.
This monoclonal recognizes both mutant forms and wild-type human p53 under denaturing conditions. It does not recognize nondenatured wild type p53. In nondenaturing conditions (IP) it only recognizes mutant p53.

The tumor suppressor protein p53 plays an important role in cancer development. The p53 protein is a transcription factor that acts as a checkpoint in the cell cycle, either preventing or initiating programmed cell death. Since cancer occurs as the malfunction in the proliferation of cells, disrupting p53 activity allows abnormal cells to multiply or allows a tumor's progression from benign to malignant. This antibody detects p53 in all mammals tested. Detection of p53 using this antibody: 50% of colon cancer sections are positive, 30% of breast cancer sections and 70% of lung cancer sections. Normal and premalignant tissues are negative.
