Product Overview
Clone EHO-9 is a rabbit monoclonal antibody that recognizes insulin gene enhancer protein ISL-1 (gene ISL1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and immunoprecipitation. The predicted molecular weight is 39.0 kDa, and the supplier reports an observed band at about 39 kDa.
ISL1 (Islet-1) is a LIM-homeodomain transcription factor that directs cell identity in several developing tissues. It is needed for pancreatic islet development, motor neuron specification, retinal ganglion cell differentiation and second heart field progenitors, and it is widely used as a marker of these cell types.

Samples with a confirmed band (WB): human K562 cells, 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 1:1000 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human liver cancer 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).
Immunogen
Synthetic peptide based on the sequence of human islet 1.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places insulin gene enhancer protein ISL-1 in the nucleus. Tissue expression noted by UniProt (human): Expressed in subsets of neurons of the adrenal medulla and dorsal root ganglion, inner nuclear and ganglion cell layers in the retina, the pineal and some regions of 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).
