Product Overview
Clone DDE-20 is a rabbit monoclonal antibody that recognizes cellular tumor antigen p53 (gene TP53) in human samples and is validated for Western blot and ICC/IF. The predicted molecular weight is 43.7 kDa, and the supplier reports an observed band at about 55 kDa.
p53 (TP53) is a tumor suppressor transcription factor that responds to DNA damage and other stresses by activating genes for cell cycle arrest, DNA repair, senescence or apoptosis. It is mutated in about half of human cancers, making it one of the most studied proteins in cancer biology, with rat models widely used alongside human cells.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
