Clone: G59-12

Isotype: IgG1

Information d'application

Indications d'application: Clone G59-12 conjugated to R-Phycoerythrin (PE) is suggested for flow cytometric analysis of p53. Positive control cell lines include SKBR-3 human breast carcinoma cells (ATCC HTB-30) and A431 human vulval carcinoma cells (ATCC CRL-1555). Jurkat T cells (ATCC TIB-152) or MCF-7 human breast carcinoma cells (ATCC HTB-22) are suggested as negative controls. Positive immunostaining is seen in a high proportion of breast and colon carcinomas. p53 staining is not typically detected in normal skin, brain, kidney, lung, stomach, or breast tissue.

Validation Images

Figure 1: Western blot analysis of U251-MG and PC3 cell line extracts using Tumor Protein P53 (TP53) antibody (Catalog number ABIN967416, Lot number 2335876). TP53 is present in the positive control sample (U251-MG) and absent from the negative control sample (PC3). The arrowhead indicates the expected position of TP53 (predicted MW ~53kDa). 32 micrograms of total protein lysates from each sample were loaded into each lane. Upper panel: scanned image of the TP53 antibody probed with the U251-MG and PC3 extracts in lanes 1 and 2 respectively. Lower panel: scanned image of the loading control (beta-actin).

Full Protocol:

• 1. Total protein extracts were boiled in 1X SDS Sample Buffer containing 1% SDS and 1.25%
• Beta-mercaptoethanol at 95°C for 5 min prior to loading.

• 3. The Spectra Multicolor Broad Range molecular mass marker (26634 Thermo Scientific) was used as a
• standard.
• 4. Proteins were then transferred onto PVDF membrane by tank transfer and protein transfer was
• confirmed with Ponceau S staining.
• 5. The immunoblot membrane was blocked in PBS containing 3% (W/V) non-fat dry milk at room
• temperature for 1 h.
• 6. The membrane was rinsed with PBS containing 0.05% Tween-20 once.
• 7. The membrane was immersed with the protein side up in the antibody solution in PBS containing 1%
• (W/V) non-fat dry milk and incubated for 2 h at room temperature (~26°C).
• 8. The membrane was rinsed in PBS containing 0.05% Tween-20 thrice for 10 min each.
• 9. The membrane was incubated in the HRP-conjugated secondary antibody solution in PBS containing
• 1% (W/V) non-fat dry milk and incubated for 1 h at room temperature (~26°C) with gentle agitation.
• 10. The membrane was rinsed thrice PBS containing 0.05% Tween-20 thrice for 10 min each.
• 11. The membrane was washed in PBS twice for 30 sec each.
• 12. Signals were detected with Pierce ECL Western Blotting Substrate (32109, Thermo Scientific). The
• blot was scanned for 300 sec.
• 13. The membrane was rinsed three times with PBS containing 0.05% Tween-20.4. Incubated in Acidic Glycine Stripping Buffer at room temperature with gentle agitation for 3 times, 10
• min each.
• 15. The membrane was washed in PBS containing 0.05% Tween-20 times for 10 min each.
• 16. Repeated Steps 5-12 with the loading control antibody (beta-actin) and its matching secondary
• antibody.

Sujet: P53 is a 53 kD nuclear phosphoprotein that acts as a tumor suppressor protein, and is involved in inhibiting cell proliferation when DNA damage occurs. The gene for p53 is the most commonly mutated gene yet identified in human cancers. Missense mutations occur in tumors of the colon, lung, breast, ovary, bladder and several other organs. The mutant p53 is overexpressed in a variety of transformed cells and the wildtype p53 forms specific complexes with several viral oncogenes including SV40 large T, E1B from adenovirus and E6 from human papilloma virus. Wildtype p53 plays a role as a checkpoint protein for DNA damage during the S-phase of the cell cycle. p53 migrates at a reduced molecular weight of 53 kDa. Clone G59-12 recognizes mutant and wild type human, rat and mouse p53 tumor suppressor protein. Recombinant full-length human p53 was used as immunogen.
