Background for p53 antibody (pAb):
p53 is the most important tumor suppressor in the genome. It is responsive to numerous genotoxic stresses, which activates its transcription factor activity, in turn causing cell-cycle arrest by activating expression of p21 Cip/WAF. Mutant
p53 that has lost its DNA-binding function interferes with the activity of native
p53 and leads to oncogenic transformation. Alternatively, transformation may be caused by overexpression of Mdm2/Hdm2, a ubiquitin ligase specific for
p53, which causes its destabilization. Inactivation of
p53 is often coincident with hyperactivation of
NFκB (
NFκB p50 and
NFκB p65), both of which serve to inhibit apoptosis.
Immunogen for p53 antibody (pAb):
This p53 antibody was raised against a synthetic peptide corresponding to amino acid residues 367-381 of human p53.
Application Notes for p53 antibody (pAb):
This p53 antibody has been validated for use in Western blotting (1:500 - 1:1,000 dilution) and immunohistochemistry (1:100 dilution). For optimal results, primary antibody incubations should be performed at 37°C. Individual optimization may be required.
Buffer:
PBS containing 0.2% gelatin, 0.01% thimersol and 0.1% sodium azide. Thimersol and sodium azide are highly toxic.
Positive Control:
Active Motif's
3T6 Swiss albino nuclear extract (Catalog No. 36002) can be used as a positive control for p53 antibody.
Compatible Secondary Antibodies:
Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP).

p53 pAb tested by Western blot.
Detection of p53 by Western blot analysis. The presence of the transcription factor p53 in nuclear extracts derived from 3T6 Swiss albino cells is confirmed using p53 rabbit polyclonal antibody at a 1:500 dilution (lane 1). The signal corresponding to nuclear p53 is eliminated when the immunizing peptide is added to the reaction (lane 2).
