Product Overview
This rabbit polyclonal antibody recognizes intersectin-1 (gene ITSN1) in human samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 195.4 kDa, and the supplier reports an observed band at about 150 kDa.
Intersectin-1 (ITSN1) is a large adaptor protein with EH and SH3 domains that links endocytosis to the actin cytoskeleton. It helps assemble clathrin-coated pits by binding dynamin and other endocytic proteins, and its long isoform acts as a guanine nucleotide exchange factor for CDC42 to promote actin assembly.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| 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 Caco-2 cells, human SiHa cells, human HeLa 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 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): A549 cells.
Samples with a confirmed signal (flow cytometry): SiHa cells.
Immunogen
Recombinant human Intersectin 1/ITSN1 fragment (Ala522–Pro1721), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places intersectin-1 in the endomembrane system, synapse, cell projection and cell membrane. Tissue expression noted by UniProt (human): Isoform 1 is expressed almost exclusively in the brain. 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).
