[Comparative study of modifications in the immunoperoxidase and immunofluorescent methods of detecting human tissue immunoglobulins].

The comparison of the data obtained by using different modifications of the immunoperoxidase and immunofluorescent methods for detecting immunoglobulins in intestinal tissues was made. The direct immunoperoxidase method was shown to allow the quantitative study of immunoglobulin-containing cells. The direct immunoperidase method was found to be technically simpler, but the indirect and complex peroxidase-antiperoxidase methods proved to be more sensitive.
