Product Overview
Clone ADO-20 is a rabbit monoclonal antibody that recognizes cellular tumor antigen p53 (gene TP53) phosphorylated at Ser9 in human samples and is validated for Western blot. The predicted molecular weight is 43.7 kDa, and the supplier reports an observed band at about 53 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.

Immunogen
Synthetic phosphopeptide around Ser9 of human p53.
Reactivity Notes
The supplier lists reactivity with human. UniProt places cellular tumor antigen p53 in the cytoplasm, nucleus, endoplasmic reticulum and mitochondrion matrix. Tissue expression noted by UniProt (human): Ubiquitous. The samples tested by the supplier (listed above) are a practical starting point for positive controls. Because the antibody is phospho-specific, signal depends on the phosphorylation state of the sample; a phosphatase-treated lysate is a useful negative control.

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).
