Mouse anti Human IgG4 (pFc subclass specific), conjugated with TRITC

Background
The reactivity of the antiserum is restricted to a subclass specific determinant on the pFc part of the IgG4 molecule as tested in direct binding enzyme immunoassay, immunoblotting, immunoprecipitation and direct immunoperoxidase staining of cytoplasmic Ig. To identify the presence of IgG4 in human serum, other body fluids, cell and tissue substrates and to determine its concentration in techniques as ELISA, indirect immunoperoxidase staining of cytoplasmic IgG4, and immunoblotting using a peroxidase labelled monoclonal antibody against TRITC. The optimum working dilution is an assay-related characteristic. It may vary widely and should always be determined by titration. For histochemical use optimum dilutions are mostly from 1:10 to 1:50; in ELISA from 1:200 upwards; in Western blotting from 1:400 upwards.

Source
Highly purified monoclonal IgG4 isolated from human serum.

Product
Purified monoclonal mouse IgG1 kappa conjugated with TRITC, lyophilized from a solution in phosphate buffered saline (pH7.2). No preservative added, as it may interfere with the antibody activity. No foreign protein added. Reconstitute the lyophilized product by adding 0.5 ml sterile distilled water.

Product Form: TRITC

Formulation: Purified monoclonal mouse IgG1 kappa conjugated with TRITC, lyophilized from a solution in phosphate buffered saline (pH7.2). No preservative added, as it may interfere with the antibody activity. No foreign protein added.

Specificity
Tetramethylrhodamine isothiocyanate-conjugated purified monoclonal Mouse antibody to Human IgG4, subclass specific. In an ELISA against human IgG subclasses, only IgG4 gave a strong positive reaction with the mouse anti-human IgG4 antibody. Reaction with human IgG1, IgG2 and IgG3 was minimal.

Species Reactivity: The antiSerum does not react with any other component of the Human Ig system or any other Human plasma protein as tested. This antiSerum has not been tested for cross-reactivity with other species.

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

Storage
The lyophilized product is shipped at ambient temperature and may be stored at +4°C; prolonged storage at or below -20°C. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). Avoid repeated thawing and freezing. If a slight precipitation occurs upon storage, this should be removed by centrifugation and will not affect the performance of the product. Diluted solutions should be stored at +4°C, not refrozen, and preferably used the same day.
