Overview
Laminin gamma Antibody (G1-3) is a research-use-only Rabbit polyclonal (rabbit origin) Rabbit IgG directed against Laminin gamma (G1-3). It is supplied for interpretation-focused detection and comparative profiling in WB, IHC. Reported localization context: Membrane, secreted (cytoplasmic in some tissue).
Key elements and design rationale
- Target context: This antibody is raised against Amino acid sequences from Laminin gamma 1-3 (NKLNEIEGSLNKAKDEMKAS + DLEERVRRQRNHLHLLETSI + LQLDSHGALHHKLRQLEEES) were used as the immunogen for the Laminin gamma antibody.. Epitope context matters because isoforms, processing, and post-translational modifications can change what is accessible in a given assay.
- Format: Antigen affinity purified. Format influences background and compatibility with different detection chemistries; conjugated formats (when present) can simplify multiplexing and reduce reliance on secondary reagents.
- Species reactivity: Human, Mouse, Rat. Cross-species performance can vary with sequence divergence and epitope conservation, so interpretation should be anchored with appropriate biological controls.
- Localization: Membrane, secreted (cytoplasmic in some tissue). Subcellular compartment context can help guide expectations in imaging assays and informs fractionation-based comparisons in lysate workflows.
- Applications: WB, IHC. These indicate assay contexts where the antibody is commonly applied; actual performance depends on sample type and processing.
Polyclonal reagents can differ in how they recognize epitope features. Monoclonal antibodies often provide more consistent epitope targeting across lots, while polyclonal preparations may broaden recognition across related epitope variants.
Biological background
Laminin gamma (G1-3) refers to the gene/protein target stated in the product record. Protein targets can exhibit context-dependent expression, regulated turnover, isoform diversity, and post-translational modifications that affect apparent molecular weight and epitope accessibility. For curated functional annotation, sequence features, and expression context, consult UniProtKB P02468, Q61092, Q9R0B6, Ensembl, and Human Protein Atlas.
Research relevance and current trends
- Integrating antibody-based detection with single-cell and spatial atlasing efforts to connect RNA programs with protein-level abundance and localization in defined cell states.
- Expanding multiplexed imaging and high-content screening, where reagent specificity, cross-reactivity risk, and channel design (including direct conjugates) become central to interpretation.
- Growing emphasis on reproducibility and application-specific validation frameworks (e.g., genetic perturbation controls, orthogonal measurements, and independent antibody strategies) when drawing mechanistic conclusions.
Common research applications
- Western blot (WB): commonly used to compare relative abundance/size (e.g., band intensity or mobility shifts) between conditions.
- Immunohistochemistry (IHC): commonly used to compare tissue- and cell-type–specific expression patterns in situ.
Interpretation typically focuses on relative differences (presence/absence, fold-changes, compartment shifts, or population-level shifts) rather than absolute quantitation. When signal changes are observed, they may reflect altered expression, altered localization/trafficking, changes in modification state, or differences in sample composition; orthogonal readouts and appropriate controls help distinguish these possibilities.
Application details (record-specific): Western Blot: 0.5-1ug/ml,IHC (FFPE): 1-2ug/ml
Application notes (record-specific): Optimal dilution of the Laminin gamma antibody should be determined by the researcher.
Notes for experimental interpretation
- Product description (record-specific): Laminins are major proteins in the basal lamina (one of the layers of the basement membrane), a protein network foundation for most cells and organs. Laminins form independent networks and are associated with type IV collagen networks via entactin, fibronectin, and perlecan. They are important and biologically active parts of the basal lamina, influencing cell differentiation, migration, and adhesion, as well as phenotype and survival. Laminins are trimeric proteins that contain an ?-chain, a ?-chain, and a ?-chain, found in five, four, and three genetic variants, respectively. Laminins critically contribute to cell attachment and differentiation, cell shape and movement, maintenance of tissue phenotype, and promotion of tissue survival.
- Potential confounders: isoforms, proteolytic processing, and PTMs can change epitope presentation and apparent size; fixation/denaturation state can also expose or mask epitopes. Species differences near the epitope may affect cross-reactivity.
- Control concepts: include genetic perturbation (KO/KD) or overexpression comparisons, orthogonal measurement (e.g., transcript or proteomics), and independent antibody/epitope strategies. For conjugated reagents, include staining-only/background controls appropriate to the detection chemistry.
Immunogen/epitope context is described as: Amino acid sequences from Laminin gamma 1-3 (NKLNEIEGSLNKAKDEMKAS + DLEERVRRQRNHLHLLETSI + LQLDSHGALHHKLRQLEEES) were used as the immunogen for the Laminin gamma antibody.. Monoclonal and polyclonal formats differ in epitope breadth; this can influence sensitivity to sequence variants, isoforms, or PTM-dependent recognition.
