Application Notes
|
To identify the presence of IgE in human serum, other body fluids, cell and tissue substrates and to determine its concentration in techniques as radio immuno assay, ELISA, indirect immuno-peroxidase and immunofluorescence staining of cytoplasmic IgE and immunoblotting. The optimum working dilution is an assay-related characteristic and should always be determined by titration. For histochemical use optimum dilutions are mostly from 1:10 to 1:100, in ELISA from 1:50 upwards, in Western blotting from 1:100 upwards. These data should be interpreted as general recommendations only. Working dilutions may vary widely, strongly depending on the test conditions.
