Supplier Product No.: 600-401-117-0.1

Supplier: Rockland

Purpose: Fibronectin Antibody

Cross-Reactivity (Details): Typically less than 1 % cross reactivity against other extracellular matrix proteins was detected by ELISA against purified standards.

Characteristics: Synonyms: rabbit anti-Fibronectin antibody, FN1, FN, Cold-insoluble globulin, CIG, Anastellin, Ugl-Y1, Ugl-Y2, Ugl-Y3

Purification: This product has been prepared by immunoaffinity chromatography using immobilized antigens followed by extensive cross-adsorption against human serum proteins and collagen and non-collagen extracellular matrix proteins to remove any unwanted specificities.

Sterility: Sterile filtered

Immunogen:

Immunogen: Fibronectin was purified from Human plasma by binding to a denatured gelatin column followed by elution with high concentrations of arginine.  The eluted material was further purified by gel filtration.  Immunization occurred after single-band purity was assessed by SDS-PAGE.

Immunogen Type: Native Protein

Isotype: IgG

Application Details

Application Notes:

Immunohistochemistry Dilution: 1:50 - 1:200

Application Note: Anti-Fibronectin antibodies have been used for indirect trapping ELISA for quantitation of antigen in serum using a standard curve, for immunoprecipitation and for western blotting for highly sensitive qualitative analysis.  Rockland's anti-Fibronectin detects intact fibronectin (Invitrogen, Cat. No. 33016-015) by western blot after digestion by Matrix Metalloproteinase-3 (MMP-3) overnight at 37° C.  Separation was performed using a 4-12 % Tris-Glycine gel.   Under these conditions a sizeable, dark band at ~220 kDa representing the undigested fibronectin, as well as many, smaller bands representing the variably sized fragments resulting from fibronectin digestion by MMP-3 were noted.  For immunohistochemistry paraffin embedded tissue preparation is recommended.

Target Details for Fibronectin 1

Target: Fibronectin 1 (FN1)

Alternative Name: FN1 (FN1 Products)

Background: Background: Human fibronectin has a molecular weight of 450,000 daltons when purified in an intact form from plasma. Fibronectin is a glycoprotein synthesized in the liver for the circulating blood plasma form, and is synthesized by many mesenchymal cells, for the extracellular matrix form. It is composed of two similar, but not identical protein chains, which are linked by two disulfide linkages at the C-terminal end of the chains. The chains are composed of domains which have specific secondary structures linked together by regions which are especially susceptible to proteolytic action. For this reason, detection by immunoblot (western) may show considerable variability in the observed apparent molecular weights, which is predicated on the source of the fibronectin, and to what degree proteolysis has occurred. Bands approximately 225 kDa should be observed after SDS-PAGE when reducing and denaturing conditions are used.
