p53 Antibody [DO-7]

CATALOG NUMBER: 33-218

Clonality:
Monoclonal
Tested Applications:
Flow, IF, IHC, WB
Host Species:
Mouse
Species Reactivity:
Bovine, Human, Monkey
Conjugate:
Unconjugated
Specifications
Host Species:
Mouse
Species Reactivity:
Bovine, Human, Monkey
Immunogen:
Recombinant human wild type p53 expressed in E. coli was used as the immunogen for this antibody. Its epitope maps within the N-terminus portion (aa 20-25) of the p53 oncoprotein.
Conjugate:
Unconjugated
Tested Applications:
Flow, IF, IHC, WB
Application Note:
Flow Cytometry: 0.5-1 ug/million cells
IF: 0.5-1 ug/ml
WB: 0.5-1.0 ug/ml
IHC (FFPE): 0.5-1.0 ug/ml for 30 minutes at RT (1)
Prediluted format : incubate for 30 min at RT (2)
The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the p53 antibody to be titered up or down for optimal performance.

1. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.
2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

User Note:
Optimal dilutions for each application to be determined by the researcher
Background:
This antibody is specific for a 53kDa protein, which is identified as p53 suppressor gene product. The large number of prolines in its amino acid sequence causes p53 to migrate slowly in SDS-PAGE, resulting in the amino acid content-estimated 43 kDa protein appearing larger than expected. DO-7 reacts with the mutant as well as the wild form of p53 under denaturing and non-denaturing conditions. It binds to MDM2, SV40 T antigen and human papilloma virus E6 protein. Positive nuclear staining with p53 antibody has been reported to be a negative prognostic factor in breast carcinoma, lung carcinoma, colorectal, and urothelial carcinoma. p53 positivity has also been used to differentiate uterine serous carcinoma from endometrioid carcinoma as well as to detect intra-tubular germ cell neoplasia.
