General description

Cellular tumor antigen p53 (p53) is a ubiquitous transcription factor that is most widely known for its function as a tumor suppressor, through its regulation of cell growth and survival. p53 is activated in response to cell stress such as DNA damage and induces either cell cycle arrest or apoptosis. It coordinates the expression of multiple genes including p21, GADD45, Bax, and Puma. p53 is regulated by multiple mechanisms: At the post-transcriptional level, the stability of p53 mRNAs is regulated by the binding of molecules such as HuR, Wig-1, RPL26, L26, and WRAP53. Post-translationally, p53 undergoes phosphorylation and acetylation which may also play a role in regulating its activity. It may also undergo ubiquitination via the Akt-MDM2 pathway resulting in degradation by the 20S proteosome. Mutations in p53 are prevalent in many types of cancers, underscoring the therapeutic relevance of this protein.

Specificity

This antibody recognizes the N-terminus of p53 (pantropic).

Immunogen

Epitope: N-terminus
Recombinant protein corresponding to human p53 (pantropic).

Application

Immunocytochemistry Analysis: A 1:500 dilution from a representative lot detected p53 (pantropic) in A431 cells.

Immunohistochemistry Analysis: A 1:1,000 dilution from a representative lot detected p53 (pantropic) in human colorectal adenocarcinoma tissue and in human prostate cancer tissue.

Immunofluorescence Analysis: A 1:1,000 dilution from a representative lot detected p53 (pantropic) in human colorectal cancer cells.

Immunoprecipitation Analysis: A representative lot was used by an independent laboratory in radiolabelled HOS cell lysate (Vojtesek, B., et al. (1995). 71(6):1253-1256.).

Immunohistochemistry Analysis: A representative lot was used by an independent laboratory in primary breast carcinoma tissue (Beck, T., et al. (1995). Gynecol Oncol. 57(1):96-104.).

Use Anti-p53 (pantropic) Antibody, clone DO-1 (Mouse Monoclonal Antibody) validated in WB, ICC, IHC, IF, IP to detect p53 (pantropic) also known as Cellular tumor antigen p53 or Antigen NY-CO-13.

Quality

Evaluated by Western Blot in A431 cell lysate.

Western Blot Analysis: 1 µg/mL of this antibody detected p53 (pantropic) in 10 µg of A431 cell lysate. This antibody detects isoforms 1, 2, and 3.

Target description

~53 kDa observed. Uniprot describes 9 different isoforms due to alternative splicing and post-translational modification. This antibody detects isoform 1 (~38 kDa), isoform 2 (~39 kDa), and isoform 3 (~39 kDa). An uncharacterized band may be observed at ~43 kDa in some cell lysates.
