Monoclonal antibody directed against p53, binding a distinct epitope in amino acids 18-27 at the N-terminus. 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. Anti-p53 Pab242 binds to an epitope within amino acids 18-27 at the N-terminus. |

| Notes |
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 Anti-p53 Pab242 binding to p53 is not inhibited by any other anti-p53 antibodies, as it binds to a sterically discrete epitope. This monoclonal works well on paraffin sections of mouse tissues. The epitope of has been mapped to the sequence 18-TFSGLWKLLP-27 in the N-terminal domain of mouse p53 (Yewdell et al., 1986; Lane et al., 1996). Concentration 1mg/ml as standard |
