IgG (Fc specific) polyclonal FITC, anti-human

Quantity: 200 µl

Background:
The reactivity of the antiserum is directed to the Fc subunit of the IgG molecule, which expresses strict (class) specificity. In immunoelectrophoresis and radial in immunodiffusion using various antiserum concentrations against human serum, a single precipitin line has been obtained which shows a reaction of identity with the precipitin lines obtained with the purified IgG used as immunogens. It does not react with IgA, IgG/Fab fragments and IgM or any non-Ig protein in human serum, as tested by immunoelectrophoresis and double radial immunodiffusion. In immunocytochemical and immunohistochemical staining of IgG at the cellular and subcellular level of appropriately treated cell and tissue substrates; to demonstrate circulating IgG antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen using a reference antibody of human origin known to be of the IgG isotype in the middle layer of the indirect 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. Working dilutions are usually between 1:20 and 1:80, depending on the method used.

Isotype: Goat Polyclonal

Source: Pools of purified IgG isolated from human serum. Freund's complete adjuvant is used in the first step of the immunization procedure.

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

Specificity:
Specificity Reference Reagent. Fluorescein isothiocyanate-conjugated IgG fraction of polyclonal Goat anti-Serum to Human IgG, Fc specific.

Reactivity: human

Cross Reactivity:
This immunoconjugate is not species-specific since inter-species cross-reactivity is a normal feature of antisera to immunoglobulins. Cross-reactivity of this antiserum has not been tested in detail.

Applications: ELISA, Immunocytochemistry, Immunohistochemistry (frozen), (In)direct immunofluorescence

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