Anti-p53 monoclonal antibody used to analyse and detect the ‘most mutated gene in cancer’, identifying transformed cell lines. Background and Research Application Anti-p53 binds p53 protein, a crucial tumour suppressor protein implicated in over 50% of cancers. p53 is a stress-regulated transcription factor that regulates cell cycle arrest and was first identified as an SV40 large T antigen-binding protein. p53 is involved in many mechanisms of anti-cancer function, and plays a role in apoptosis, genomic stability, cell cycle regulation and inhibition of angiogenesis. p53 is known as the guardian of the genome as it functions to prevent gene mutation. Mutants of p53 which frequently occur in human cancers fail to recognise their DNA binding site, leading to the loss of tumour suppressor activity. p53 is typically found in low levels in healthy cells due to its short half-life, however in disease states it is expressed in high amounts due to somatic mutations and believed to contribute to transformation and malignancy. p53 mutations are found in over 50% of cancers with germline mutations, offering a predisposition to inherited cancer susceptibility syndrome. Understanding the functions of mutant p53 can help in the development of new therapeutic approaches that may be useful in a broad range of cancer types. DO-14 binds to an epitope within the central region of p53 between amino acids 110 - 286 defining a cryptic epitope exposed in unfolded/ denatured p53. |

Production Details Purified using multi-step affinity chromatography with protein A. Storage Conditions Store at -20 degrees frozen. Avoid repeated freeze/thaw cycles. Points of Interest Nine isoforms of human p53 are produced by alternative splicing and promotor usage, the epitope recognized by clone DO-14 is present in all isoforms.
