• Antibody identity: Polyclonal (rabbit origin); Rabbit IgG.
• Conjugate/label: Unconjugated (affects detection chemistry and multiplex compatibility).
• Format: Antigen affinity purified.
• Species reactivity: Mouse, Rat.
• Listed applications: WB, ELISA (refer to on-page specifications for application-specific guidance).

Biological background

Heparin-binding EGF-like growth factor (HB-EGF), also called Diphtheria toxin receptor (Dtr) is a member of the EGF family of proteins that in humans is encoded by the HBEGF gene. Enables epidermal growth factor receptor binding activity; growth factor activity; and heparin binding activity. Involved in positive regulation of keratinocyte migration; positive regulation of smooth muscle cell proliferation; and wound healing, spreading of epidermal cells. Acts upstream of or within several processes, including epidermal growth factor receptor signaling pathway; positive regulation of peptidyl-tyrosine phosphorylation; and regulation of heart contraction. Located in extracellular space. Is integral component of plasma membrane. Is expressed in several structures, including branchial arch; heart; oral region gland; telencephalon; and tooth. Human ortholog(s) of this gene implicated in glomerulosclerosis and perinatal necrotizing enterocolitis. Orthologous to human HBEGF (heparin binding EGF like growth factor).

Research relevance and current trends

• Comparative expression profiling across cell types, tissues, or perturbations (e.g., drug treatment, genetic editing, or differentiation).
• Subcellular localization and trafficking studies, including co-localization with pathway markers in microscopy-based assays.
• Integration of protein-level measurements with transcriptomics or proteomics to relate abundance to regulation and phenotype.

Common research applications

• Western blotting: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.
• ELISA: researchers commonly compare relative signal levels across conditions and use appropriate negative/positive controls for interpretation.

Interpretation should account for antibody-dependent factors such as epitope accessibility, isoforms, and sample preparation differences across workflows.

Notes for experimental interpretation

• Isoforms and PTMs: many targets have multiple isoforms and post-translational modifications that can shift apparent signal or localization; interpret bands/signals accordingly.
• Epitope context: binding can depend on protein conformation and sample processing; region information in the title/immunogen can help anticipate what may be detected.
• Species differences: predicted or validated reactivity may vary by ortholog sequence and sample context; confirm in your model system.
• Control concepts: include negative controls (no-primary/isotype), and where possible genetic controls (KO/KD) or independent antibodies to strengthen conclusions.

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).
