Tested Applications WB

Applications Validated by Active Motif: WB*: 1:500 - 1:2,000 dilution *Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western blot. For p53, we also offer AbFlex p53 Recombinant Antibody (rAb). For details, see Catalog No. 91247.

Background Information

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 NFkB (NFkB p50 and NFkB p65), both of which serve to inhibit apoptosis.
