Application Notes
|
To identify the presence of IgM in human serum, other body fluids, cell and tissue substrates and to determine its concentration in techniques as ELISA, direct immunoperoxidase staining of cytoplasmic IgM, and immunoblotting. 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 1:50 to 1:200, in ELISA from 1:250 upwards, in Western blotting from 1:500 upwards. These data should be interpreted as general recommendations only.
