General description

Monoclonal anti-p53, (mouse IgG2b isotype) is derived from the hybridoma DO-7 produced by the fusion of mouse myeloma cells (SP2 cells) and splenocytes from BALB/c mice immunized with recombinant human wild type p53. The p53 gene is located on chromosome 17p. The p53 protein is highly conserved and expressed in normal tissues.

Application

Monoclonal Anti-p53 antibody produced in mouse has been used in:
  • immunoblotting
  • enzyme linked immunosorbent assay (ELISA)
  • immunocytochemistry
  • immunohistochemistry
  • immunoprecipitation

Biochem/physiol Actions

Elevation of p53 protein induces the transcriptional activation of multiple genes, including p21waf1. p21waf1 (cyclin-dependent kinase inhibitor 1A) interacts directly with cyclin dependent kinases, important for cell cycle progression, thereby inhibiting their activity and resulting in cell cycle arrest.
p53 is a transcription factor that regulates several critical cellular functions such as DNA repair, apoptosis, and cell cycle arrest. p53 primarily functions as a tumor suppressor and inactivates apoptosis inhibitors such as survivin, MCL-1 and BCL-2. Mutations in p53 gene occur most commonly in a wide range of human cancers. Thus, analysis of p53 function has important implications in cancer pathogenesis and therapy . Monoclonal Anti-p53 antibody specifically reacts with p53 in humans.

Physical form
