Product Overview
This rabbit polyclonal antibody targets tyrosine-protein kinase ZAP-70 (gene ZAP70) in human, mouse and rat samples and is validated for IHC and Western blot. The predicted molecular weight is 69.9 kDa, and the supplier reports an observed band at about 70 kDa.
ZAP-70 is a SYK-family tyrosine kinase that is recruited to phosphorylated ITAMs of the T cell receptor–CD3 complex after antigen recognition. Activated ZAP-70 phosphorylates adaptors such as LAT and SLP-76 to launch downstream T cell signaling, it is essential for thymocyte development, and it is studied in immunodeficiency and as a marker in chronic lymphocytic leukemia.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
Samples with a confirmed band (WB): human Jurkat cells, human CCRF-CEM cells, human MOLT-4 cells, human Raji cells, rat spleen tissue, rat thymus tissue, mouse spleen tissue, mouse thymus 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 prostate 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).
Immunogen
Synthetic peptide from the middle region of human ZAP70. It differs from the mouse sequence at two residues.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places tyrosine-protein kinase ZAP-70 in the cytoplasm and cell membrane. Tissue expression noted by UniProt (human): Expressed in T- and natural killer cells. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
