Product Overview
This rabbit polyclonal antibody recognizes tumor protein 63 (gene TP63) in human samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 76.8 kDa, and the supplier reports an observed band at about 75 kDa.
p63 (TP63) is a p53 family transcription factor that exists as multiple isoforms with or without an N-terminal transactivation domain. The ΔNp63 isoforms are master regulators of basal epithelial stem cells and are essential for skin, limb and craniofacial development. p63 is a widely used marker of basal and myoepithelial cells.

Samples with a confirmed band (WB): human A431 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human oesophagus squama cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): A431 cells.
Samples with a confirmed signal (flow cytometry): A431 cells.
Immunogen
Recombinant human p63 fragment (Ser311–Glu680), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 98%.
Reactivity Notes
The supplier lists reactivity with human. UniProt places tumor protein 63 in the nucleus. Tissue expression noted by UniProt (human): Widely expressed, notably in heart, kidney, placenta, prostate, skeletal muscle, testis and thymus, although the precise isoform varies according to tissue type. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
