Fibrinogen polyclonal, anti-rat

Quantity: 1 ml

Background:
The reactivity of the antiserum is restricted to rat fibrinogen molecule. In immunoelectrophoresis and radial immunodiffusion, using various antiserum concentrations against normal rat plasma a single precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified fibrinogen. No reaction is obtained with any other plasma protein components or serum. However, the antiserum may also react with fibrin monomers, circulating fibrinopeptides and fibrin degradation products. As unlabelled primary or secondary antibody reagent for the indirect detection of fibrinogen in rat cells, tissues and body fluids in immunofluorescence and immunoenzyme methods; for the production of immunoconjugates with a selected marker; to prepare insoluble immunoaffinity adsorbents by coupling to an artificial carrier; as catching or detection reagent in non-isotopic methodology and solid phase immunochemistry (e.g. ELISA, Western blotting).When applied in any cytochemical or histochemical procedure or solids phase coupling technique, the optimum concentration of the IgG preparation should always be established by titration.Typical working dilutions in histochemistry are usually between 1:50 and 1:250; in ELISA and comparable non-precipitating antibody-binding assays between 1:500 and 1:5,000.

Isotype: Goat Polyclonal

Source: Fibrinogen (clotting factor I) is a heat labile beta glycoprotein present in plasma. It is the precursor of fibrin, which is the key protein constituting the network of the blood clot. Thrombin converts fibrinogen to fibrin by limited proteolysis. Fibrin monomers polymerize to fibrin which is stabilized by cross-linking. Fibrinogen is isolated from fresh plasma after removing prothrombin. Freund's complete adjuvant is used in the first step of the immunization procedure.

Form: Purified hyperimmune IgG, in phosphate buffered saline (PBS, pH 7.2)

Specificity:
Purified IgG fraction of polyclonal Goat anti-Serum to Rat fibrinogen.

Reactivity: rat

Cross Reactivity:
The antiserum does not cross-react with any other component of Rat plasma. Inter-species cross-reactivity is a normal feature of antibodies to plasma proteins since they frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail.

Applications: Indirect immunofluorescence, ELISA, Dot blot, Immunoblotting

Storage: Store at 4C, or in small aliquots at -20C.
