Product Overview
This rabbit polyclonal antibody recognizes actin nucleation-promoting factor WAS in human, mouse and rat samples and is validated for IHC, ICC/IF and Western blot. The predicted molecular weight is 52.9 kDa, and the supplier reports an observed band at about 53 kDa.
WASP is an actin nucleation-promoting factor expressed in blood cells. Activated by CDC42, it stimulates the Arp2/3 complex to build branched actin networks needed for immune synapse formation, migration and phagocytosis. Mutations cause Wiskott–Aldrich syndrome, an immunodeficiency with small platelets and eczema.

Validated Applications
| Immunocytochemistry / Immunofluorescence | 0.5–1 µg/mL (Human) |
|---|---|
| IHC (frozen sections) | 0.5–1 µg/mL (Human) |
| IHC (paraffin sections) | 0.5–1 µg/mL (Human) |
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
Samples with a confirmed band (WB): human HL-60 cells, human U937 cells, human Jurkat cells, human MCF-7 cells, rat liver tissue, mouse RAW264.7 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 lung 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 citrate buffer (pH 6).
Samples with confirmed staining (IHC): human placenta tissue.
Samples with confirmed staining (ICC/IF): a549 cells.
Immunogen
Synthetic peptide from the C-terminal region of human WASP. It differs from the mouse sequence at two residues.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places actin nucleation-promoting factor WAS in the cytoplasm and nucleus. Tissue expression noted by UniProt (human): Expressed predominantly in the thymus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
