General description

Purified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with SP2 mouse myeloma cells (see application references). Recognizes the ~53 kDa mutant p53 protein under non-denaturing conditions. Recognizes both the mutant and the wild-type p53 protein under denaturing conditions.
Recognizes the ~53 kDa mutant p53 protein under non-denaturing conditions by immunoprecipitation, immunofluorescence, and flow cytometry. Recognizes both mutant and wild-type p53 by immunoblotting and paraffin sections under denaturing conditions.
This Anti-p53 (Ab-3) (Mutant) Mouse mAb (PAb240) is validated for use in FC, Frozen Sections, Gel Shift, Immunoblotting, IF, IP, Paraffin Sections for the detection of p53 (Ab-3) (Mutant).

Immunogen

Human
a recombinant protein consisting of amino acids 14-389 of p53 fused to β-galactosidase

Application

Under non-denaturing conditions (immunoprecipitation, immunofluorescence and frozen sections), Anti-p53 (Ab-3) does not recognize normal (wild-type) p53 protein; it recognizes an epitope exposed by activating mutations or denaturation. In denaturing protocols (immunoblotting and paraffin sections), Anti-p53 (Ab-3) will recognize both mutant and wild-type p53. Will not recognize to some p53 molecules with mutations in the RHSVV epitope, but will react to TFIIIA, which has the RHSVV epitope. For gel shift assay, use Cat. No. OP29L and resuspend in 100 µl buffer. Antibody should be titrated for optimal results in individual systems.

The cytoskeleton of senescent cells was systematically studied using senescent and young fibroblasts. In the cell senescence, skin fibroblasts extraordinarily produced vimentin in contrast to actin and tubulin, which were down-regulated. Among the focal adhesion proteins, paxillin and c-Src decreased

Lung cancer is the leading cause of cancer deaths worldwide. Expression of the p53 tumor suppressor protein is frequently altered in tobacco-associated lung cancers. We studied chemopreventive effects of p53-modulating agents, namely, CP-31398 and Prima-1, on 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)-induced lung adenoma

We previously reported that phenethyl isothiocyanate (PEITC), a dietary-related compound, can rescue mutant p53. A structure-activity relationships study showed that the synthetic analog 2,2-diphenylethyl isothiocyanate (DPEITC) is a more potent inducer of apoptosis than natural or synthetic ITCs. Here, we
