IgG1 IgG2a IgG2b IgG2c IgA IgM (Fc specific) polyclonal, anti-rat

Quantity: 200 µl

Background:
The reactivity of the antiserum is directed to the Fc subunit of the major immunoglobulin isotypes (classes and subclasses) which expresses strict isotypic (class) specificity. In immunoelectrophoresis and double radial immunodiffusion using various antiserum concentrations against normal rat plasma and serum, the characteristic IgG, IgA and IgM precipitin lines are obtained. In immunocytochemical and immunohistochemical staining of immunoglobulins at the cellular and subcellular level of appropriately treated cell and tissue substrates; to demonstrate circulating antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen using a reference antibody of rat origin in the middle layer of the indirect test procedure; in non-isotopic assay methodology (e.g. ELISA) to measure immunoglobulins in rat serum or other body fluids. The absence of activity to the common Ig/Fab subunit prevents the reaction of this conjugate with immunoglobulins bounds to Fc receptors on non-lymphoid cells. As a second step an avidin or streptavidin conjugate of the user's choice has to be used.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.Working dilutions for histochemical and cytochemical use are usually between 1:100 and 1:500; in ELISA and comparable non-precipitating antibody-binding assays between 1:1,000 and 1:5,000.

Isotype: Goat Polyclonal

Source: Purified normal IgG, IgA and IgM isolated from pooled rat serum. Freund's complete adjuvant is used in the first step of the immunization procedure.

Form: Biotin-coupled hyperimmune goat IgG, in phosphate buffered saline (PBS, pH 7.2).

Specificity:
Biotin-conjugated IgG fraction of polyclonal Goat anti-Serum to Rat IgG, IgA and IgM, Fc specific

Reactivity: rat

Cross Reactivity:
Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail.

Applications: ELISA, Immunocytochemistry, Immunohistochemistry (paraffin), Dot blot, Immunoblotting

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