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.
Attributs du produit
Tetramethylrhodamine isothiocyanate-conjugated purified monoclonal mouse antibody to human IgG4, subclass specific Fluorochrome/IgG protein molar ratio (F/P) approximately 2.7.
Purification
Purified
Immunogène
Highly purified monoclonal IgG4 isolated from human serum.
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. Working dilutions may vary widely, strongly depending on the test conditions. These data should be interpreted as general recommendations only.

Conseil sur la manipulation
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 ascites should be stored at +4 °C, not refrozen, and preferably used the same day.
