Key antibody attributes include Mouse, Monoclonal (mouse origin), clone 11E4., isotype Mouse IgG1, kappa. Applications listed for this product include IF, WB, FACS. Reported/annotated localization context: Cell surface, cytoplasmic, cell junctions. Species reactivity (as provided): Human, Mouse.
Key elements and design rationale
- Target: PLAKOGLOBIN (Gamma Catenin) — 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: Mouse, Monoclonal (mouse origin), clone 11E4., isotype Mouse IgG1, kappa — these attributes help align secondary reagents and controls (e.g., isotype-matched controls) with your assay design.
- Localization: Cell surface, cytoplasmic, cell junctions — expected subcellular distribution can guide band/structure interpretation and help flag off-target signal.
- Product notes (from provided description): It recognizes a protein of 80-87kDa, identified as gamma-Catenin or Plakoglobin. The catenins (α, β, γ and δ) are ubiquitously expressed, cytoplasmic proteins that associate with E-cadherin at cellular junctions. Catenin/cadherin complexes play an important role in mediating cellular adhesion. α T-catenin, also referred to as VR22, is a 895-amino acid protein that is most abundantly expressed in cardio-myocytes and in the peritubular myoid cells of the testis. α T-catenin binds to α E-catenin as well as to β-catenin, and it functions to inhibit Wnt signaling. CTNNA3, the gene that encodes for α-T-catenin, is located on chromosome 10, and mutations in this gene show a strong correlation to late-onset Alzheimer s disease (LOAD) as well as to dilated cardiomyopathy.
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, PLAKOGLOBIN is positioned within ECM & Cell Adhesion, Alzheimer’s, Cardiomyopathy research contexts. Localization annotations (e.g., Cell surface, cytoplasmic, cell junctions) 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
- IF: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
- WB: 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, IF/ICC localization, Flow cytometry staining, Specificity controls.
- Workflow notes: Validate CATENIN by Western blot in cell/tissue lysates (include controls), Detect CATENIN localization by IF/ICC in cultured cells (optimize fixation + dilution), Quantify CATENIN-positive cells by flow cytometry in…
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.
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).
