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.
