Clone: Polyclonal
Background: The reactivity of the antiserum is directed to the Fc subunit of the IgG molecule. In immunoelectrophoresis and double radial immunodiffusion, using various antiserum concentrations against normal guinea pig plasma and serum, a single characteristic precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified IgG. No reaction is obtained with purified IgA, IgM and IgG/Fab fragments. In direct staining of cytoplasmic IgG in fixed guinea pig cells and tissue substrates; to identify circulating IgG antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen or immune complex using a reference antibody of guinea pig in the middle layer of the test procedure. This immunoconjugate is not pre-diluted. The optimum working dilution of each conjugate should be established by titration before being used. Excess labelled antibody must be avoided because it may cause high unspecific background staining and interfere with the specific signal.
Source: Purified normal IgG isolated from pooled guinea pig serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Specificity: Fluorescein isothiocyanate–conjugated IgG fraction of polyclonal Sheep antiSerum to Guinea Pig IgG, Fc specific.
Formulation: FITC-coupled purified hyperimmune sheep IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2). No preservative added, as it may interfere with the antibody activity.
