Product Overview
This rabbit polyclonal antibody recognizes homeobox protein cut-like 1 (gene CUX1) in human and mouse samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 164.2 kDa, and the supplier reports an observed band at about 200 kDa.
CUX1 (also called CDP or Cut-like 1) is a homeodomain transcription factor with several DNA-binding cut repeats. It often acts as a repressor of developmentally regulated genes and, in the brain, controls dendrite branching, spine formation and synaptogenesis in upper cortical layers. It is a common marker of cortical layer II-III neurons and is studied in development and cancer.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human, Mouse) |

| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human K562 cells, human HeLa cells, human MCF-7 cells, human SH-SY5Y cells, mouse stomach 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 placenta tissue, human thyroiditis tissue, human laryngeal squamous cells carcinoma tissue, mouse colon 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): HepG2 cells.
Immunogen
Recombinant human CUX1 fragment (Met1–Glu220), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt places homeobox protein cut-like 1 in the nucleus. 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).
