Goat IgG anti-Mouse IgG+IgM+IgA (Fc)-Biotin, MinX none

The reactivity of the antiserum is directed to the Fc subunit of the major immunoglobulin isotypes which expresses strict isotypic (class) specificity. In immunoelectrophoresis and double radial immunodiffusion using various antiserum concentrations against normal mouse 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 mouse origin in the middle layer of the indirect test procedure, in non-isotopic assay methodology (e.g. ELISA) to measure immunoglobulins in mouse 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 is 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.
