Product Overview
This rabbit polyclonal antibody recognizes serine/threonine-protein kinase PAK 3 (gene PAK3) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 62.3 kDa, and the supplier reports an observed band at about 62 kDa.
PAK3 is a brain-enriched serine/threonine kinase activated by CDC42 and RAC1. In neurons it supports dendritic spine formation and synapse plasticity, and mutations in the X-linked PAK3 gene are associated with intellectual disability.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human, Mouse, Rat) |
| Immunocytochemistry / Immunofluorescence | 5 µg/mL (Human) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human placenta tissue, human PANC-1 cells, human U2OS cells, human PC-3 cells, rat brain tissue, mouse brain tissue.
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 thyroid papillary carcinom tissue, mouse brain tissue, rat brain 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): MCF-7 cells.
Samples with a confirmed signal (flow cytometry): PC-3 cells.
Immunogen
Recombinant human PAK3 fragment (Met1–Asp263), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places serine/threonine-protein kinase PAK 3 in the cytoplasm. Tissue expression noted by UniProt (human): Restricted to the nervous system. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
