Product Overview
This rabbit polyclonal antibody targets tyrosine-protein kinase ITK/TSK in human samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 71.8 kDa, and the supplier reports an observed band at about 72 kDa.
ITK (IL-2-inducible T-cell kinase) is a Tec family tyrosine kinase expressed in T cells and NK cells. After T-cell receptor activation, it phosphorylates PLCγ1, driving calcium flux and transcription factor activation. ITK shapes T-cell development and the balance between helper T-cell subsets, and it is studied in T-cell signaling.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |

Samples with a confirmed band (WB): human Jurkat cells, human MOLT-4 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 spleen 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).
Samples with a confirmed signal (flow cytometry): HEL cells.
Immunogen
Recombinant human ITK fragment (Arg49–Phe465), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places tyrosine-protein kinase ITK/TSK in the cytoplasm and nucleus. Tissue expression noted by UniProt (human): T-cell lines and natural killer cell lines. 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).
