Key elements and design rationale

• Target: EHD3 (EH domain-containing protein 3) — selectivity and interpretation should be considered in the context of isoforms, post-translational modifications, and related family members when applicable.
• Format: Purified — format can influence background, multiplexing compatibility, and downstream detection strategies.
• Antibody identity: Rabbit, Polyclonal (rabbit origin), isotype Rabbit IgG — these attributes help align secondary reagents and controls (e.g., isotype-matched controls) with your assay design.
• Localization: Cell membrane, cytoplasmic — expected subcellular distribution can guide band/structure interpretation and help flag off-target signal.
• Product notes (from provided description): Eps15 homology domain-containing protein 3, abbreviated as EDH3 and also known as PAST3, is a protein encoded by the EHD3 gene. The Eps15 homology (EH) domain-containing protein family consists of four members, EHD1, EHD2, EHD3, and EHD4. The chromosomal locations of the human EHD genes are as follows: EHD1 maps to 11q13, EHD2 maps to 19q13.3, EHD3 maps to 2p21, and EHD4 maps to 15q11.1 (1-3). The encoded proteins of all EHD family members contain multiple conserved regions, which include an amino-terminal nucleotide-binding consensus site, a bipartite nuclear localization signal, and a carboxy-terminal EH protein-binding domain with an EF-hand motif (3,4). EHD1 is ubiquitously expressed with increased expression in testis (2,3). EHD2, EHD3, and EHD4 have more specific expression with EHD2 highly expressed in heart, EHD3 expressed in brain, kidney, liver, placenta, ovary, and heart, and EHD4 expressed in heart, placenta, and pancreas (1,5,6). The EHD proteins may participate in ligand-induced endocytosis (3-5).

Where multiple assay formats are possible, align the antibody format, host/isotype, and listed applications with your detection system and controls to support clear interpretation of signal.

Biological background

In this catalog, EHD3 is positioned within Renal & Urology, Kidney disease research contexts. Localization annotations (e.g., Cell membrane, cytoplasmic) can help contextualize expected signal patterns in imaging and fractionation-based readouts. For authoritative gene/protein nomenclature, domains/isoforms, and curated functional annotations, consult resources such as UniProt, NCBI Gene, and Ensembl.

Research relevance and current trends

• Higher-plex and spatially resolved readouts (e.g., multiplex IF/IHC, spatial omics) are increasing demand for well-characterized primary antibodies with clearly stated host/isotype and labeling strategies.
• Genetic perturbation controls (knockout/knockdown) and orthogonal measurements (e.g., RNA vs protein) are commonly used to strengthen target attribution when interpreting antibody-derived signals.
• Reproducibility initiatives emphasize transparent reporting of antibody identity (clone, host, isotype) and experimental context to improve cross-study comparability.

Common research applications

• WB: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• IHC-P: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• IF: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• FACS: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• Typical workflow themes: Western blot validation, IHC on FFPE tissue, IF/ICC localization, Flow cytometry staining, Specificity controls.
• Workflow notes: Validate EHD3 by Western blot in cell/tissue lysates (include controls), Detect EHD3 by IHC in FFPE tissue sections (optimize antigen retrieval + dilution), Detect EHD3 localization by IF/ICC in cultured cells (optimi…

When comparing conditions, consistent sample processing and appropriate negative/positive controls support interpretation of qualitative localization differences and quantitative abundance changes.

Notes for experimental interpretation

• Isoforms and post-translational modifications may shift apparent molecular weight or epitope accessibility, especially across cell states or treatments.
• Species and tissue context can affect sequence conservation, expression level, and background binding; predicted reactivity should be verified in your sample.
• Control concepts include isotype-matched controls, secondary-only controls (for indirect detection), and genetic/orthogonal controls (e.g., KO/KD, independent antibodies, or RNA measurements) when feasible.

Monoclonal and polyclonal antibodies can differ in epitope recognition breadth and lot-to-lot characteristics; consider clonality and clone information (when provided) alongside your assay requirements. Conjugated formats may simplify detection but can change background and multiplexing behavior compared with unconjugated primaries.
