Overview
Fibronectin Antibody is a research-use primary antibody intended for detection of FIBRONECTIN in experimental workflows. It is supplied in Purified format. Key antibody attributes include Mouse, Monoclonal (mouse origin), clone TV-1, isotype Mouse IgG1, kappa. Applications listed for this product include FACS, IF, IHC-P. Reported/annotated localization context: Connective tissue matrix. Species reactivity (as provided): Human.
Key elements and design rationale
- Target: FIBRONECTIN — 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 TV-1, isotype Mouse IgG1, kappa — these attributes help align secondary reagents and controls (e.g., isotype-matched controls) with your assay design.
- Localization: Connective tissue matrix — expected subcellular distribution can guide band/structure interpretation and help flag off-target signal.

Product notes (from provided description): Fibronectin is a soluble dimeric glycoprotein of 440kDa, which is present in cells, extracellular matrix, and blood. There are two types of fibronectin: soluble fibronectin which is produced by hepatocytes and found in blood plasma, and insoluble cellular fibronectin which is produced by fibroblasts in a soluble form and latter assembled into an insoluble form via fibril formation.
This antibody reacts with the cellular as well as plasma form of fibronectin. Reportedly, after iv administration, this antibody localizes to tumor vessels where it binds to the underlying basement. The Fibronectin epitope recognized by this antibody is not accessible in normal tissues to the circulating antibody indicating that it can be used to specifically target tumor vessels in vivo. Clone TV-1 fibronectin antibody is reportedly useful for delivering vasoactive agents to tumors to induce increased vascular permeability or blood flow prior to treatment with chemotherapeutic drugs or antibodies.
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, FIBRONECTIN is positioned within Molecular & Cellular Biology, Tumor research contexts. Localization annotations (e.g., Connective tissue matrix) 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
- FACS: 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.
- IHC-P: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
- Typical workflow themes: IHC on FFPE tissue, IF/ICC localization, Flow cytometry staining, Specificity controls.
- Workflow notes: Detect FIBRONECTIN by IHC in FFPE tissue sections (optimize antigen retrieval + dilution), Detect FIBRONECTIN localization by IF/ICC in cultured cells (optimize fixation + dilution), Quantify FIBRONECTIN-positive cell…
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).
