Preparation And Storage

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

Recommended Assay Procedures

Clone G59-12 conjugated to R-Phycoerythrin (PE) is suggested for flow cytometric analysis of p53 (Cat. No. 557027). 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.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  3. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
  4. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.
  5. Please refer to for technical protocols.

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. The G59-12 clone was originally characterized by western blot analysis, immunoprecipitation and immunohistochemical staining.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
