Western Blotting Image 1: Fibronectin/FN1 (E5H6X) Rabbit mAb (BSA and Azide Free)
Western blot analysis of extracts from various cell lines using Fibronectin/FN1 (E5H6X) Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower). The absence of Fibronectin/FN1 expression in PANC-1 cell extracts is consistent with molecular and proteomic expression profiling data, confirming specificity of the antibody. Data were generated using the standard formulation of this product.

Product Information

Product Usage Information

This product is the carrier free version of product #26836. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.

This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN, or CUT&Tag assays. If you require a carrier-free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.

BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.

Formulation

Supplied in 1X PBS (10 mM Na2HPO4, 3 mM KCl, 2 mM KH2PO4, and 140 mM NaCl (pH 7.8)). BSA and Azide Free.

For standard formulation of this product see product #26836.

Storage

Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.

Specificity / Sensitivity

Fibronectin/FN1 (E5H6X) Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total Fibronectin/FN1 protein.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a protein fragment corresponding to residues near the carboxy terminus of human Fibronectin/FN1 protein.

Background

Fibronectin is a multi-domain extracellular matrix (ECM) protein. The protein uses its different domains to bind distinct ECM components such as collagens, growth factors, and cell surface integrins to carry on its functions (1). Fibronectin has been implicated in many essential biological processes, including tissue repair, fibrosis, and tumor development (1,2). There are many fibronectin isoforms. Plasma fibronectin is synthesized by hepatocytes and exists as a compact, inactive conformation in the bloodstream. It is a major component of fibrin clots. Upon binding to integrins or other cell surface receptors, fibronectin switches to an extended conformation, and exposes its function domains to activated extracellular matrix assembly (3). Fibroblasts, endothelial cells, and many types of cancer cells have also been shown to synthesize cellular fibronectin isoforms. Among them, the EDA or EDB isoforms are particularly highly expressed during fibrosis and cancer development, and are potential diagnostic and therapeutic targets (4-6).
