Alternate Names for p53 Antibody

  • BCC7
  • FLJ92943
  • LFS1
  • LFS1TRP53
  • p53 tumor suppressor

  • transformation-related protein 53
  • TRP53
  • tumor protein p53
  • Tumor suppressor 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.

FAQs for p53 Antibody (NB200-171). (Showing 1 - 1 of 1 FAQs).

  1. I would like to know how you set the lot number of these antibodies. When does the lot number change and what is the difference between lots. Is every lot being QC tested? Or dependent on the host animals (in polyclonal)?
    • The lot numbers for our products, including NB200-104 and NB200-171, change with every purification or production. So each lot number will refer to the particular purification batch (if the antibody is provided purified) or production batch (if the antibody is not purified). The antibodies are QC tested every lot to ensure specificity and reactivity.
