Product Overview
Clone 23T77 is a rabbit monoclonal antibody that recognizes transcription factor AP-2-alpha (gene TFAP2A) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 48.1 kDa, and the supplier reports an observed band at about 48 kDa.
AP-2α (TFAP2A) is a transcription factor that binds GC-rich AP-2 sites as a dimer. It is particularly important in neural crest cells and for development of the face, eye, limbs and body wall, and TFAP2A mutations cause branchio-oculo-facial syndrome.

Samples with a confirmed band (WB): human SIHA cells, human A431 cells, human 293T cells, rat C6 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Synthetic peptide based on the sequence of human AP2 alpha.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places transcription factor AP-2-alpha in the nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

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).
