Product Overview
This rabbit polyclonal antibody detects pituitary homeobox 2 (gene PITX2) in human, mouse and rat samples and is validated for Western blot and flow cytometry. The predicted molecular weight is 35.4 kDa, and the supplier reports an observed band at about 35 kDa.
PITX2 is a paired-like homeodomain transcription factor that acts downstream of Nodal signaling to establish left-right asymmetry of internal organs. It also guides development of the eyes, teeth, pituitary and muscle, and its mutations cause Axenfeld-Rieger syndrome, while variants near PITX2 are associated with atrial fibrillation.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
Samples with a confirmed band (WB): human Caco-2 cells, human HEK293 cells, human U2OS cells, human HeLa cells, human A549 cells, human U-87MG cells, rat heart tissue, mouse RAW2467 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, 50 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 1:10000, ECL detection.
Samples with a confirmed signal (flow cytometry): 293T cells.
Immunogen
Synthetic peptide from the N-terminal region of human PITX2/RGS. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places pituitary homeobox 2 in the nucleus and cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
